Guidelines for Tanning Equipment Owners, Operators and Users

Acknowledgements

These guidelines have been reviewed by and published in collaboration with the Federal Provincial Territorial Radiation Protection Committee (FPTRPC). The FPTRPC comprises a forum of delegates from the following government organizations: Canadian Nuclear Safety Commission, Department of National Defence, Employment and Social Development Canada (Canada Labour Program), Health Canada and Provincial and Territorial radiation protection programs. The committee was established to support federal, provincial and territorial government radiation protection agencies with their respective mandates in Canada. The mission of the committee is to advance the development and harmonization of practices and standards for radiation protection within federal, provincial and territorial jurisdictions. We wish to thank those organizations for the many hours of research, review and consultation put into preparing the following Guidelines for Tanning Equipment Owners, Operators and Users.

FPTRPC Position Statement on Ultraviolet Radiation

Whereas,

  • There is sufficient scientific evidence demonstrating that excessive exposure to ultraviolet (UV) radiation, from sunlight or from artificial sources, causes acute and chronic adverse health effects;
  • The main organs affected by UV radiation are the skin and the eyes;
  • Exposure to solar and artificial UV radiation is widely recognized as an important, and preventable, cause of skin cancer;
  • There is significant scientific evidence indicating that long-term exposure to UV radiation without adequate eye protection also plays a role in the development of some types of cataract and other eye and skin conditions;
  • There is increasing evidence indicating that UV radiation also acts as a systemic immunosuppressor;
  • Artificial sources of UV radiation can be found in work and recreation environments and the use of tanning equipment can add to the total dose of UV radiation absorbed by the body;
  • The UV radiation dose to the population can be significantly decreased by applying simple strategies and measures to reduce exposures to the sun and artificial sources of UV radiation; and,
  • The World Health Organization (WHO) has classified all UV radiation as a Class 1 carcinogen, which includes sunlight (1992) and tanning equipment (2009). The WHO does not recommend the use of UV tanning devices for cosmetic purposes.

The FPTRPC does not endorse UV radiation-induced tanning and recommends protective measures against excessive exposure to solar and artificial UV radiation, such as those contained in this document, be implemented by health, education, labour and recreation authorities in all provinces and territories and adopted by the general public. The FPTRPC further recommends that the use of tanning equipment, particularly by minors, be restricted.

Preface

There is no such thing as a safe or healthy tan as tanning results from the skin’s natural defense response to damage caused by exposure to ultraviolet (UV) radiation. Exposure to UV A and B radiation can cause sunburn, premature skin ageing, skin cancers, cataracts and other eye and skin diseases. It has also been shown to weaken the body’s immune system.

Individuals choosing to use tanning equipment (sunlamp or tanning bed) should be aware of the hazards and health risks involved so they can make informed decisions about the amount of exposure they receive.

This guideline is designed to give tanning equipment owners, operators and users a fundamental understanding of UV radiation and its effects on health. It outlines general guidelines in the context of the risks associated with tanning and provides information on certain cosmetic and medicinal products that increase UV effects.

Manufacturers, sellers, importers and distributors of tanning equipment have specific requirements for compliance under the federal Radiation Emitting Devices Act and the Radiation Emitting Device Regulations (Tanning Equipment). For reference, sections 1 through 17 of the above mentioned Regulations are provided in Appendix A. Only tanning equipment that complies with the Regulations should be used for tanning purposes.

This document provides further guidance on tanning equipment usage, however it should not be considered sufficient on its own and should not be considered as an endorsement for the use of tanning equipment. Operators are required to take any additional measures necessary to minimize health hazards in their establishment. Additional information is available through regional public health authorities, or through members of the FPTRPC:

Tanning Safety Guidelines and Recommendations

Owners and operators of tanning equipment should be aware of and adhere to the requirements for tanning equipment as outlined under the Radiation Emitting Devices Regulations (Tanning Equipment) (Appendix A), and refer to them as needed. In addition, owners, operators and users of tanning equipment should follow the guidelines listed below which have been developed specifically for their adherence.

General

  1. Children under 18 years of age should not use tanning equipment. Depending on provincial or territorial regulations, a minor may have restricted access to tanning equipment.
  2. All tanning equipment sold, resold, leased or imported into Canada must comply with the requirements specified for tanning equipment under the federal government’s Radiation Emitting Devices Regulations (see Appendix A). Owners should check with their equipment supplier to ensure that tanning equipment and any associated apparatus being purchased and used by either themselves or by others, are in compliance with the Regulations.
  3. Knowledgeable and trained tanning equipment operators or salon staff members should always be on the premises while tanning equipment is in use. Operators should be aware of skin typing and exposure procedures. Operators and users should be familiar with these guidelines and recommendations, as well as municipal and/or provincial/territorial public health and public safety regulations to inform and assist the public in the safer use of tanning equipment. Tanning salon operators should ensure that their employees receive adequate training including certification programs, where available, on the operation of tanning equipment.
  4. Tanning equipment operators should ascertain a client’s ability to tan (i.e. skin type), history of sunburns and skin cancer, history of skin infections, rashes or other skin conditions (e.g. open wounds or lesions) as well as any photosensitizing agents (see Appendix B) they may be using prior to or during the time of exposure.
  5. Tanning salon operators should maintain client records. This information is to be used for exposure planning and to assist clients in understanding how the factors that impact one’s ability to tan relate to UV radiation. Users and operators should follow the exposure schedules recommended by the manufacturer.
  6. Users should avoid sunbathing and the use of tanning equipment on the same day. Users should also avoid the use of infrared saunas or warming beds for at least 24 hours following substantial sun exposures or tanning with artificial sources as it may increase the risk of developing skin cancer. Infrared radiation alone has been shown to induce erythema, skin pigmentation (in certain skin types) and skin photoaging, which can augment the harmful effects of UV radiation.
  7. Individuals identified as Skin Type I (Always Burn, Never Tan) should not use UV-emitting tanning equipment. Those with light skin who can tan, but who burn easily and severely, are strongly discouraged from using tanning equipment, as they are most susceptible to sunburn among those who can develop a tan. Tanning equipment operators should inform prospective clients in this regard. Individuals with skin infections, rashes or other skin conditions should not use tanning equipment without first consulting a health care provider.
  8. Prior to use of tanning equipment, the owner/operator of the tanning equipment should make users aware of the risks of tanning equipment including that a delayed, adverse reaction to UV exposure, such as red, irritated and watering eyes, an itching skin rash or sunburn may result. Delayed reactions can develop anywhere from minutes to a day and a half following exposure. In the event of a serious adverse reaction reported to the tanning establishment or owner/operator, the user should be advised to consult their health care provider. Upon receipt of notification of an adverse reaction, the owner/ operator should investigate the incident and implement modifications as necessary.

    All such incidents should be documented and made available to an appropriate regulatory official on request. Where an injury to an individual is reported to the owner/operator by a duly qualified health care provider as a result of an exposure to the tanning equipment under the owner’s control, the owner shall inform the relevant health authority. See Appendix C for a sample injury reporting template.

  9. Tanning beds are to be operated/maintained by an onsite and trained operator as required by the province/territories. Self‐serve unmanned machines are not to be used in a commercial environment. It is recommended that all equipment be controlled by remote timing devices.
  10. It is recommended that tanning equipment users be informed of these guidelines and advised to consider discussing the risks of artificial tanning with their health care providers.

UV Lamps (also referred to as UV Bulbs)

First and maximum exposure times per session recommended for skin types I through VI are dependent upon the strength and type of UV emissions from the lamps used in individual pieces of tanning equipment. Different models and brands of UV lamps produce varying intensities and emissions of UVA, UVB and small amounts of UVC radiation. Cases of overexposure and burns from UV radiation have occurred as a result of client exposure to tanning equipment where original lamps have been replaced with newer, more powerful lamps that do not comply with federal regulations.

  1. Operators should ensure that replacement UV lamps function identical to the original bulbs supplied with the tanning equipment at the time of sale, lease or import so that the UVC irradiance (i.e. 200 ≤ λ < 260 nm) does not exceed a ratio of 0.003 of the UVB irradiance (i.e. 260 ≤ λ ≤ 320 nm)Footnote 1  .  Modern tanning equipment should not emit UVC radiation or at least comply with the UVC/UVB ratio outlined in the Radiation Emitting Devices Regulations (Tanning Equipment) under Functioning Standards and comply with the UVC limits in the International Electrotechnical Commission (IEC) Standard 60335-2-27.
  2. Lamps in tanning equipment should never be replaced by lamps of different, often higher, levels of UVA and UVB. In order to avoid injury, replacement UV lamps must function so that maximum exposure time remains within plus or minus 10% of the maximum exposure time originally recommended by the manufacturer. When replacement lamps are identical to the original ones, the client can rely on the manufacturer’s information provided with tanning equipment.  As High Intensity Discharge (HID) lamps require special filters to block harmful portions of the UV spectrum, it is important to replace any cracked or damaged filters in order to prevent harm to the user.
  3. The operator should ensure that:
    • a. The maximum exposure time recommended by the manufacturer is not increased to compensate for decreasing UV intensity as lamps age.
    • b. First and maximum exposure times comply with the manufacturer’s recommendation. Owners, operators, and users should be made aware that every machine has its own number of lamps and irradiance spectrum (ratio between UVA and UVB), making the exposure schedule specific for each type of equipment.

Protective Measures

  1. UV radiation warning labels, compliant with the Radiation Emitting Devices Regulations (Tanning Equipment), must be clearly visible on each piece of tanning equipment. Adherence to current labeling requirements, as specified in the Radiation Emitting Devices Regulations, is required for the sale, lease and importation of used tanning equipment with labels designed to warn users about UV radiation and its harmful effects on health.  Labels should remain on the equipment as placed by the manufacturer.  Provincial or territorial regulations for commercial tanning establishments may require the use of the latest federal warning label in some manner.  Depending on provincial or territorial regulations, additional signage on equipment, doorways, or at point-of-sale may be required. A copy of these guidelines should be available within facilities or in the client reception area. 
  2. Each tanning device must have a control to allow the person being exposed to easily turn off the tanning equipment at any time without the need to disconnect the electrical plug or remove the UV lamp (as per the Radiation Emitting Devices Regulations (Tanning Equipment)).
  3. The operator should provide each client/customer with UV radiation safety eyewear that meets or exceeds the requirements in the Radiation Emitting Devices Regulations (Tanning Equipment) and covers the eyes securely. Eyewear should be made available for purchase, with instructions given on proper use and fit, and the operator should check that clients have eyewear with them at every session.
  4. Protective eyewear used with sunlamps or tanning equipment should meet three criteria. The eyewear should have a spectral transmittance that is:
    • not more than 0.001 over the wavelength range from 200 to 320 nm; and
    • not more than 0.01 over the wavelength range from 320 to 400 nm.
  • In addition, eyewear transmittance should be sufficient over wavelengths greater than 400 nm to enable the user to read the labels and use the controls mentioned in the requirements. According to the IEC Standard (IEC 60335-2-27, Edition 5.2, 2015-04; Table 101)Footnote 2  the maximum transmission of light with wavelengths between 400 to 500 nm should not exceed 5 percent in order to minimize retina damage due to extensive blue-light exposure.
  1. A physical barrier, such as a clear UV-transmitting plexiglass cover, should always be in place between the lamps and the individual being exposed to UV radiation, covering the top and bottom sections of a two-part, hinged tanning bed or covering the side sections of a vertically mounted booth. A physical barrier constructed of acrylic is also acceptable if it prevents direct physical contact between the user and the UV lamps in a horizontal device. This barrier will prevent injury to the user of the equipment in case of accidental lamp breakage. It will also guard against thermal burns from close contact with the lamps.
  2. It is recommended that tanning equipment owners follow manufacturers' repair and maintenance schedules to ensure devices are kept within manufacturers' specifications or the operational standards of the Radiation Emitting Devices Regulations (Tanning Equipment).  Tanning equipment should always be turned off during maintenance (e.g., changing UV lamps, cleaning equipment, etc.). In the event that the lamps must remain on, employees should use protective eyewear and clothing to minimize exposure.
  3. Adequate ventilation should be provided such that the temperature of the tanning booth does not exceed 30°C.
  4. Common contact surfaces, including protective eyewear, should be disinfected between each use, to prevent infection. Disinfectants should not leave films behind after use and the product used must state that it is an effective disinfectant against bacteria and viruses. The product must not damage the plastic in the protective eyewear or the plexiglass barrier. Tanning pillows should be replaced if the outer covering is compromised (i.e. cracked, ripped, split open exposing the inner foam which may encourage infection).  Individuals may contact their Provincial/Territorial public health officials for further guidance:

What is UV Radiation?

Optical radiation is part of the electromagnetic spectrum and a form of non-ionizing radiation that can exhibit properties of both waves and particles (photons). These may, as in the case of visible light, or may not, as in the case of ultraviolet or infrared light, be detectable by the human eye depending on their particular wavelength.

UV radiation is part of the invisible electromagnetic spectrum with wavelengths ranging from 400 to 100 nm (nm stands for nanometer which is one billionth of a meter). While UV radiation has a longer wavelength and less energy than X-rays, it has a shorter wavelength and is more energetic than visible light.  The UV part of the spectrum is divided into three components; UVA, (400 to 320 nm), UVB, (320 to 280 nm) and UVC (280 to 100 nm).  Depending on its wavelength, UV radiation may trigger different biological effects and will penetrate skin tissue to different degrees (more deeply in the case of UVA than UVB or UVC) (See Figure 1).

Figure 1.

This diagram depicts the region of the electromagnetic radiation spectrum representing ultraviolet radiation.  Visible light and infrared radiation regions are also shown. Ultraviolet radiation is further divided into three portions: high energy ultraviolet C (with shorter wavelengths between 100 and 280 nanometers), ultraviolet B (with wavelengths between 280 and 320 nanometers), and finally lower energy ultraviolet A (with longer wavelengths between 320 and 400 nanometers). Visible light is the only region in the electromagnetic radiation that can be detected by the human eye and is seen as a variety of colours. These colours include violet, blue, cyan, green, yellow, orange and red, with each colour corresponding to a different wavelength. Violet has the shortest wavelength, starting around 400 nanometers, while red has the longest wavelength, ending around 700 nanometers. Wavelengths between 700 nanometers and 1000 nanometers (1 millimeter) make up the infrared region of the electromagnetic spectrum.

 

UVA – ultraviolet A radiation has a wavelength range of 320 to 400 nanometres which is closest to the “blue-end” of the light spectrum. UVA has to be 1000 times more intense than UVB to trigger the same erythema level, but UVA penetrates deeper into the dermis potentially causing damage to the underlying vascular system and dermal support structures. It is the most common radiation used in commercial tanning equipment and is responsible for the immediate darkening of the melanin already present in the skin. An intense exposure to UVA can result in burns in sensitive people. UVA rays can cause premature skin ageing due to their penetration in the dermis. Most tanning beds emit between 10-70 mW/cm² UVA, which is 2 to 14 times more than the sun at noon in the summer. Some high speed/high intensity tanners (e.g. facial) could emit even more UVA in some cases emitting greater than 30 times more than the Canadian summer sun.

UVB – ultraviolet B radiation has a wavelength range of 280 to 320 nanometres. UVB rays can penetrate the epidermis and are mostly responsible for sunburns (being 1000 times more erythemally effective than UVA) as well as for delayed tanning that appears within 2 or 3 days and lasts for a longer period of time. UVB is found at varying levels in all commercial types of tanning equipment. Always remember that the letter “B” in UVB reminds one of “burn”. Most tanning beds emit similar levels of UVB to the noon-time summer sun however some pieces of tanning equipment can emit as much as 10 times more UVB radiation than others so they can cause serious burns in a very short period of time.

UVC – ultraviolet C radiation (100 – 280 nanometres) is hazardous to all forms of life, even with only very short exposures. UVC radiation from the sun is completely absorbed by the ozone layer in the higher atmosphere and never reaches the earth’s level. Modern tanning equipment should not emit UVC radiation or at least comply to the UVC/UVB ratio dictated in the Regulations.

The sun is a major source of UV radiation, emitting mostly UVA and a small amount of UVB. Fortunately, the sun’s emissions of the most energetic and harmful form of UV radiation, UVC, does not reach the Earth’s surface. Other than natural sources, UV radiation can also come from a variety of different man-made products. Artificial sources may include certain lamps (e.g. incandescent, halogen, fluorescent, UV emitting LEDs etc.), UV curing devices, welding equipment, UV lasers, and tanning equipment.

Tanning equipment contains tanning lamps that emit mostly UVA radiation with a small amount of UVB. UV radiation from a tanning lamp is often generated within the fluorescent bulb by exciting the atoms of an inert gas with electricity. Portions of unwanted UV can be converted into visible light by having it transfer its energy into the phosphors deposited on the inside of the bulb. The percentage of UVA and UVB can vary from bulb to bulb depending on manufacture, operating temperature, wattage, and lamp age.

Tanning Lamps

Low Pressure Tanning Lamps

Low pressure fluorescent lamps are the most common in the tanning industry and can vary in size, length and UV output, emitting UVA and UVB, as well as visible light and some heat (infrared). The intensity of UV radiation from low pressure lamps can often exceed the sun’s UV intensity several-fold, which is why exposure times in a tanning bed should be controlled by a knowledgeable or trained operator as required by the province/territories.

High Pressure Tanning Lamps

High pressure lamps, also referred to as High Intensity Discharge (HID) lamps, are less common than low pressure fluorescent lamps and are relatively small in size in comparison. HID lamps produce UV radiation by means of an electric arc between tungsten electrodes within a quartz or alumina enclosure containing a pressurized gas with some metal salts. HID lamps emit considerably higher amounts of visible, UVA and UVB, than fluorescent lamps and also emit dangerous amounts of UVC radiation. As such, HID lamps require a filter during operation to prevent severe burning and skin damage. Typically, HID lamps are used for facial tanning and often have shorter exposure times due to their higher UV emissions. The manufacturer's exposure schedule should be adhered to when using HID lamps to prevent injury (see “Exposure Schedules” on page 18).

Skin and the UV-induced Tanning Process

Skin is the largest organ of the body; its primary purpose is to protect the underlying tissues against harm from the environment (e.g. infection, toxins, physical injury, UV radiation, etc.) while maintaining the internal environment (e.g. temperature, humidity, etc.). Skin is comprised of two layers, the epidermis (outer layer) and the dermis (inner layer). The innermost section, or dermis, is formed of tissues containing nerves, blood vessels, lymphatics and fatty tissue. The outer layer, or epidermis, constitutes a series of layers. Skin cells, mostly consisting of keratinocytes, are created in the bottom or innermost layer of the epidermis. As cells age, they travel from the innermost layer of the epidermis to the outer surface of the skin where they die. The surface layer (or stratum corneum) forms a tough outer protective covering. As the cells move outward, they lose moisture, flatten and eventually flake off the surface of the skin in a process that takes approximately 28 days. It is the epidermis that is primarily involved in the tanning process.

Skin Types

Knowledge of skin type is important when discussing tanning as tanning ability is dependent on skin type. Skin types are often described using the Fitzpatrick skin type classification system. This system helps to identify an individual’s skin sensitivity to UV radiation based on that individual’s natural skin colour. However photosensitivity is not only determined by constitutive skin pigmentation but is subject to other factors including genetic disposition for photosensitivity independent of skin colour, history of skin cancer, frequency of UV exposure, and use of agents (e.g. drugs, cosmetics etc.) that may increase one’s photosensitivity (refer to Appendix B).

Fitzpatrick classification is grouped into 6 skin types, ranging from very fair (skin type I) to very dark (skin type VI), described as follows:

  • Skin type I: Always burns, never tans, extremely sensitive skin. This skin type is often found in people with red hair, fair to pale skin, freckles and blue eyes. People with this skin type should not use tanning equipment.
  • Skin type II: Usually burns, tans minimally. This skin type is often found in people with fair-haired, fair skin, and blue or hazel eyes.
  • Skin type III: May burn, tans well. This skin type is represented by the average Caucasian with fair skin.
  • Skin type IV: Rarely burns, tans well, and exhibits immediate pigment darkening. This skin type is often found in people with dark brown hair, naturally tinted or light brown pigmented skin, and dark coloured eyes.
  • Skin type V: Very rarely burns, tans easily and well, and exhibits immediate pigment darkening. This skin type is often found in people with dark brown hair, brown to dark pigmented skin, and dark coloured eyes.
  • Skin type VI: Very rarely burns, tans easily and well, and exhibits immediate pigment darkening. This skin type is often found in people with very dark hair, very dark skin, and dark coloured eyes.

Although subjective, Fitzpatrick skin type classification is used in artificial tanning to determine an individual’s exposure schedule and maximum exposure time based on their skin’s natural colour in order to avoid injury from burning or erythema (skin reddening) but still deliver a sufficient UV radiation dose necessary to develop and maintain a tan.

For this reason, the exposure schedule provided by the tanning equipment manufacturer takes into account exposure times, intervals between exposures and the degree of sensitivity for each skin type. The manufacturer recommended exposure times are weighed in accordance to the erythema reference action spectrum. The recommended exposure time of the first tanning session for untanned skin is based on an initial dose not exceeding 100 Joules per square metre (J/m²) to consider the more sensitive skin types and the recommended maximum exposure time is based on a dose not exceeding 625 J/m². The minimum interval between consecutive exposures and the maximum number of minutes of exposure per year based on a dose not exceeding 15 kilojoules per square metre (kJ/m²) can be found on a label affixed on the tanning equipment device.

It is the responsibility of the owner/operator of the tanning equipment to follow the manufacturer’s exposure schedule by referring to the guide/label provided by the manufacturer for that particular tanning device to avoid injury.

Tanning from Exposure to UV Radiation

A tan is a response to excessive UV radiation exposure which could create prolonged skin damage or skin cancer. Protection from a tan is limited and overexposure (sunburn) can occur. The user should be educated on the limitations of protection afforded by a tan.

There are two effects that occur in the skin following exposure to UV radiation. The first effect, immediate tanning or immediate pigment darkening (IPD), is a change in skin pigmentation which occurs immediately or shortly after exposure to UV radiation (primarily by UVA). This results from photo-oxidation and darkening of the melanin pigment present in the epidermis. This tan is only temporary and fades within 3 to 36 hours after exposure. A second process known as “delayed tanning” occurs in most individuals when the skin is exposed to UVB radiation, but not in people who lack the ability to produce sufficient amounts of melanin in the skin (i.e. Skin type I). An inability to tan increases the risk of skin cancerFootnote 3 , therefore individuals with Skin Type 1 should not use tanning equipment.

There are two processes involved in delayed tanning.

  1. Melanocytes (skin cells capable of producing melanin pigment) are produced at the base of the epidermis with each melanocyte producing melanosomes containing the melanin pigment. These melanin containing units begin to spread throughout the layers of the skin as they work their way toward the keratinocytes at the surface of the skin. Melanin-containing cells cause the skin to appear darker in colour.
  2. The tough outer surface layer of dying skin cells thickens and absorbs more of the UVB radiation. This process serves as a protective mechanism in order to minimize further damage.

The above processes can take place over the course of a day and produce a noticeable tan within a few days that can last for weeks or months.

Exposure Schedules

The exposure schedule is designed to allow a client to gradually build a tan, while minimising the risk of erythema. As per the Regulations, the initial dose must not to exceed 100 J/m², weighted according to the ISO 17166:1999 (CIE S 007/E:1998) erythema action spectrum, for the first exposure session for untanned skin, gradually increasing over the following sessions to a maximum of 625 J/m² per session. The total amount of time (minutes) of exposure must not exceed the annual recommended dose of 15 kJ/m², weighted according to the CIE erythema action spectrum. The schedule is based on the skin type of the user and the output of UV-emitting lamps in the tanning unit. The exposure schedule displayed on the equipment provided by the equipment manufacturer should be followed for each particular product and skin type.

The recommended schedule within the international standard IEC 60335-2-27 Ed. 5.2 2015-04 follows that the initial dose should not exceed 100 J/m² for untanned skin and that a waiting period of 48h should be respected between the first and second exposure to allow time to check for unexpected side effects. The recommended dose for the second exposure should not exceed 250 J/m². A single tanning course, consisting of a consecutive series of exposures, should not exceed a total dose of 3 kJ/m², weighted according to the erythema action spectrum, with the annual dose not exceeding 15 kJ/m². For more information regarding exposure scheduling, refer to the IEC 60335-2-27 Ed. 5.2 2015-04.

Furthermore, it is prudent to use gradual increments of approximately 100 J/m² per week until a maximum of 625 J/m² per session is reached. If any skin reddening (erythema) is visible 16-24 hours after any exposure, then further exposures should cease and may be continued the following week with the advice of a health care provider.

Risks of UV-Induced Tanning

Darkening of the skin (tanning) from exposure to UV is a biological response to UV radiation damage. Although UV radiation may provide some limited health benefits, including the treatment of certain skin conditions and specific autoimmune diseases, and help in the formation of vitamin D, the FPTRPC does not consider tanning a healthy activity. Whether from the sun or from tanning equipment, UV radiation can pose a risk to one’s health.

Overexposure to UV has been linked to the following negative health outcomes:

  • sunburns
  • premature skin aging
  • skin/eye cancer
  • eye damage
  • weakening of the immune system

The risks associated with UV-induced tanning outweigh the benefits as there is no clear threshold between positive and negative health effects and an individual’s response is dependent upon a number of biological or physical variables which differ from person to person (e.g., skin type) and are subject to environmental conditions. Studies indicate that individuals who frequently tan are at greater risk of developing skin cancer later in life since the damage from UV exposure is cumulative and there is an escalating risk with total hours, sessions or years of tanning equipment use. Age of first use of tanning equipment is linked to an increased risk of developing melanoma and early onset of the disease.

Adverse health effects from overexposure to UV radiation include the following:

Sunburn

Sunburn (or erythema) is an inflammatory redness of the skin caused by too much exposure to UV radiation, particularly UVB radiation. The small blood vessels in the skin dilate and increase blood flow to the skin’s surface, resulting in redness and pain. The reaction can be almost immediate in severe cases, or may develop up to 24 hours later in less severe cases of overexposure. Delayed reactions, depending on the severity of the burn, include the skin shedding the upper layer of damaged skin and blistering. These responses to UV may render the skin more susceptible to infection. Individuals with open wounds or lesions are particularly sensitive to UV radiation as the protective epidermal layer is compromised. Studies indicate that people who have suffered severe and frequent sunburns during childhood are at greater risk of developing skin cancer later in life.

Phototoxic and Photoallergic Reactions

A phototoxicity and photoallergy reaction is often an abnormal skin reaction to exposure from light or to UV radiation. Photoallergic reactions can manifest 24 to 72 hours following exposure to drugs and light/UV, often resulting in a rash resembling dermatitis. However, phototoxic reactions are more common and can occur rapidly following exposure, often resembling severe sunburn; the severity of which is dependent on the amount of the applied substance or photo-radiation. Examples of phototoxic and photoallergic reactions include, but are not limited to, hydroa vacciniforme, actinitic prurigo, solar urticarial (solar 'hives' erythema), and polymorphic light eruption (allergic reaction to UV). Also, pre-existing conditions such as chronic actinic dermatosis, atopic eczema and psoriasis can be exacerbated by either solar or artificial UV radiation exposure. Individuals with lupus erythematosus, porphyria, or xeroderma pigmentosum are particularly sensitive and are encouraged not to use tanning equipment. Individuals who have the inability to tan or are deemed photosensitive should avoid tanning equipment. A number of drugs and/or cosmetics have also been shown to have phototoxic or photoallergic effects. The list of products that can cause photosensitivity is extensive and described in Appendix B.

Premature Skin Aging

UV radiation causes actinic elastosis or premature ageing effects such as skin wrinkling, thinning of the skin, pigmentary change and loss of elasticity giving it a more leathery appearance. UV radiation can also cause the development of actinic keratoses which are scaly or crusty skin growths that resemble warts, often appearing on UV-exposed areas such as the face, scalp, lips, and the back of the hands. If left untreated, these growths may become cancerous.

Skin Cancer

Skin cancer is the most common form of cancer in Canada. In 2016, there were an estimated 6,800 new cases of melanoma--the most deadly form of skin cancer. In the time period from 2010-2015, an average of 77,800 new cases of non-melanoma skin cancers per year were reported. More than ever, skin cancer seems to occur in younger individuals. Non-melanoma skin cancers, such as squamous and basal cell carcinomas, are most common, but rarely fatal, and in most cases, caused by UV exposure. Melanoma is a less common, but potentially deadly form of skin cancer. The main factors that predispose an individual to the development of melanoma include recreational exposure to either solar or artificial UV radiation, history of sunburn or history of skin cancer.

More information on Canadian cancer statistics is available at:

https://www.canada.ca/en/public-health/services/chronic-diseases/chronic-disease-facts-figures.html

Non-melanoma skin cancer

Squamous Cell Carcinoma (SCC) is an uncontrolled growth of abnormal squamous cells, which comprise most of the skin’s upper layers of the epidermis. SCC is not as common as Basal Cell Carcinoma but tends to be more aggressive since this type of skin cancer can spread to other parts of the body if not treated promptly. SCCs are less harmful than melanoma and can be identified as elevated growths with a central depression, scaly red patches, open sores, or have a wart-like appearance that may easily bleed, crust or ulcerate. SCCs are most often found on areas on skin that are frequently exposed to the sun.

Basal Cell Carcinoma (BCC) is the most common form of non-melanoma skin cancer and the least fatal of all the skin cancers. Its appearance may be that of a red, pale or pearly colored round or flattened lump or scaly area that may form an ulcer with time. It tends to grow slowly, usually on areas on skin frequently exposed to the sun.

Melanoma skin cancer

Melanoma which is comprised of cancerous melanocytes (cells containing the melanin pigment) is the third most common type of skin cancer, and the deadliest form. Exposure to UV radiation and heredity plays a role in the development of melanoma. There are four types melanoma:

  • Superficial spreading melanoma, the most common form, typically stays within its area of origin before growing radially across the skin surface.
  • Nodular melanoma, a more invasive form of melanoma, develops from superficial melanoma, growing downwards through the skin towards the basal layers.
  • Lentigo maligna melanoma, a melanoma that has evolved from a lentigo maligna, typically presents on chronically sun damaged skin such as the face and the forearms of the elderly.
  • Acral lentiginous melanoma, a type of lentiginous (a pigmented spot of melanocyte hyperplasia) skin melanoma, which although rare in Caucasians and people with lighter skin types, is the most common subtype in people with darker skins.

In 2009, international experts from the WHO International Agency for Research on Cancer (IARC), found significant evidence of an association between artificial tanning and the development of non-melanoma and melanoma skin cancer types. The IARC determined that the use of tanning equipment can increase the risk of developing cutaneous melanoma by 59% if first exposure occurs prior to 35 years of ageFootnote 4 . The risk of developing skin cancer was also found to increase with cumulative exposure to UV radiation, i.e., there is an escalating risk with total hours, sessions or years of tanning equipment use. The WHO, IARC, the International Commission on Non-ionizing Radiation Protection (ICNIRP), and the Scientific Committee on Consumer Products (SCCP) to the European Commission have recommended that the use of tanning equipment should be avoided for children, adolescents and in individuals who have a diminished ability to tan. In light of scientific evidence, the WHO placed UV radiation emitting tanning equipment into its highest cancer risk category to a Group 1 (“carcinogenic to humans”).

Eye Problems

UV radiation may cause painful temporary injuries to the cornea and conjunctiva; called photokeratitis and photoconjunctivitis respectively. These conditions may develop two to twenty-four hours following exposure, with typical occurrence within six to twelve hours. UVA radiation may cause eye ageing effects, such as browning of the lens and its loss of elasticity with overexposure to UVB likely contributing to the appearance of cataracts in the lens. Repeated exposures can lead to the development of skin cancer around the eyes, pre-cancerous growths (e.g. pterygium) of the outer white part of the eye, conjunctival cancer or intraocular melanoma. Vision loss due to macular degeneration, while a risk factor, is predominantly caused by prolonged exposure to blue light in the visible spectrum, which is often a component of non-exclusive UV emitting sources. Proper use of eyewear when using tanning equipment will reduce risk of eye injuries.

Weakened Immune System

Exposure to UV radiation weakens the immune system. UV-induced immunosuppression takes place both locally (i.e. skin) and systemically (i.e. the whole body), and has the potential to decrease the body's ability to defend itself against infection and serious illnesses, including skin cancer (i.e. non-melanoma and malignant melanoma) and other non-skin related types of cancer. The immunosuppressive nature of UV can be used to treat autoimmune diseases, for example, mycosis fungoides (also known as Alibert-Bazin syndrome or granuloma fungoides), a form of cutaneous T-cell lymphoma that can be treated with UV radiation exposure under controlled conditions. Similarly, phototherapy can be a treatment option for some types of eczema; an inflammatory skin condition.

Glossary of Terms

Actinic elastosis
also known as solar elastosis - a disorder associated with photoaging and refers to the accumulation of thickened malformed elastin fibers in the dermis in response to long-term exposure to UV radiation. The disorder is characterized by thickened, dry, rough, yellowish-colored, skin with deep creases and fine wrinkles.
Actinic keratosis
also known as solar keratosis which is often identified as rough, scaly elevated lesions (resembling a wart) caused by repeated exposure to the UV radiation from the sun and as a result can be often found on frequently sun exposed areas of the skin. If left unchecked, lesions may develop into skin cancer.
Delayed tanning
a type of tanning produced by UVB appearing a few days after exposure and lasting up to a few weeks. This process increases the number of melanocytes in the skin. At the same time, these melanocytes increase their production of melanin which then is oxidized giving the tanned appearance.
Dermis
lowest (innermost) layer of cells in the skin under the epidermis.
Epidermis
outer layers of skin in which melanin is found, and where tanning occurs.
Erythema
the medical term for inflammatory redness of the skin. It is the result of an exposure to UV radiation, particularly UVB. It is commonly called “sunburn”.
Fitzpatrick skin type
A skin type classification system based on one’s natural skin colour (I-VI) that is used to determine tanning ability or photosensitivity. Originally designed for phototherapy to reduce the risk of sunburns/overexposure during treatment.
Immediate tanning
also known as immediate pigment darkening (IPD) - a photo-oxidation process (mainly triggered by UVA) that causes rapid darkening of the melanin pigment already present in the skin with the change in pigmentation often lasting only for a short time (hours to days).
MED - Minimum Eythemal Dose
a measure of the accumulated erythemally weighted UV energy that would cause the first perceptible sign of reddening (i.e., erythema). The energy-equivalent depends on the skin type. For the most sensitive skin types, 1 MED is approximately 2 SED. For skin type II 1 MED is approximately 2.5 SED.
Melanin
a pigment that responsible for the color of our skin, hair, and eyes. Darker skin is associated with higher levels of melanin. Melanin is an effective absorber and scatterer of light, providing some protection to skin cells from UV radiation.
Melanogenesis
the production of melanin by cells called melanocytes. In the skin, melanogenesis occurs after exposure to UV radiation, causing the skin to visibly tan.
Melanoma
also known as Cutaneous Malignant Melanoma (CMM) - the most serious (potentially fatal) but rarest form of skin cancer that occurs in melanocytes (pigment containing cells in the skin).
Non-Melanoma Skin Cancer(NMSC)
the most common type of skin cancer that occurs in either basal or squamous cells. Of the two types of non-melanoma skin cancers, Basal Cell Carcinoma (BCC) is the most common often occurring on frequently sun exposed areas of the body and develops in the cells lining the bottom of the epidermis near the dermis. Squamous Cell Carcinoma (SCC) develops in the cells lining the top of the epidermis and is also commonly found on frequently exposed areas of the skin but can spread to other parts of the body.
Photokeratitis and photoconjunctivitis
painful injuries to the cornea (the clear front window of the eye that covers the iris and pupil) and conjunctiva (a thin transparent membrane that covers white part of the eye) respectively, caused by overexposure to UV radiation that can be avoided by wearing protective eyewear.
Photosensitivity
a person’s biological sensitivity or reactivity to visible light or UV radiation.
Pterygium
a benign growth of the conjunctiva that can invade the cornea which can affect vision.
SED
Standard Erythemal Dose is a measure of the accumulated erythemally-weighted UV energy, where 1 SED = 100 J/m²
Stratum corneum
tough outer layer of dead skin cells.
Ultraviolet (UV) radiation
defined as the part of the non-ionizing invisible electromagnetic spectrum which ranges from 400 nm to 100 nm. Tanning occurs as a result of exposure to UV radiation.
