UVA radiation from gel nail UV lights
The use of ultraviolet (UV) lamps in nail salons has raised concerns about the potential risk of cancer from the ultraviolet radiation they emit. These lamps, commonly known as UV nail lamps, are used to speed-dry regular manicures and are essential for setting gel manicures. There are two main types of lamps used in salons: light-emitting diode (LED) lamps and UV nail lamps with fluorescent bulbs. Despite their names, both types of lamps emit UV radiation, primarily in the form of UVA rays.
Additionally, a mathematical model developed by Diffey, which combined age and UV exposure data, estimated that a significant number of women would need to use UVA nail lamps daily to develop squamous cell carcinoma (SCC) on the back of their hands. Furthermore, a study by John C Dowdy et al. concluded that there was only a moderate risk associated with UV nail lamp use during the permissible daily exposure time. These findings suggest that while UVA radiation from gel nail UV lights may pose a cancer risk, the likelihood of developing skin cancer from occasional exposure is relatively low.
To mitigate the potential risks associated with UVA radiation from gel nail UV lights, some precautions can be taken. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to the hands 20 minutes before UV light exposure. Additionally, wearing fingerless gloves during the manicure can provide added protection for the skin. It is also worth noting that the type of UV lamp and its wattage can impact the amount of UV radiation emitted, with higher-wattage lamps emitting more radiation.

The risk of skin cancer
While the link between UV exposure and skin cancer is well-established, the specific risk associated with nail salon lamps has been a subject of debate. Studies have shown that the connection between nail salon lamps and cancer is not as strong as previously thought. The exposure time to these lamps is typically brief, and the UV radiation levels are relatively low. However, it is important to note that the risk may vary depending on the type of lamp, the wattage, and the duration of exposure.
Research on the potential carcinogenic effects of gel manicures is still ongoing. Some studies suggest that the level of UVA exposure from a gel manicure every two weeks is unlikely to significantly increase the risk of skin cancer. Additionally, the nail plate has been found to block a significant portion of UVB rays, further reducing the potential risk. However, it is important to consider that any form of repeated UV radiation exposure could potentially have carcinogenic effects.
To mitigate the risk of skin cancer from gel nail UV lights, several precautions can be taken. Applying a broad-spectrum, water-resistant sunscreen with SPF50 or higher to the hands and nails before exposure to UV light is recommended. Wearing fingerless gloves during the manicure process can also provide protection. Additionally, some salons offer lower-wattage UV lamps or LED lamps, which emit lower levels of UV radiation. It is also important to be mindful of UV exposure from natural sunlight and take appropriate protective measures when outdoors.

Preventative measures
While the connection between nail salon UV lamps and cancer is not very strong, it is still important to take preventative measures to protect yourself from the UV radiation emitted by these devices. Here are some ways to do that:
Apply Sunscreen: Applying sunscreen is one of the most effective ways to protect your skin from UV radiation. It is recommended to use a water-resistant, broad-spectrum sunscreen with an SPF of 50 or higher. Apply the sunscreen to your hands and any other exposed areas of skin, such as your face and arms, about 20 minutes before your manicure to allow it to absorb and provide adequate protection. Remember to reapply sunscreen as directed, especially if you spend time outdoors after your manicure.
Wear Fingerless Gloves: Fingerless gloves can provide a physical barrier between your skin and the UV light. Many salons now offer these gloves to their customers. Wearing fingerless gloves during the manicure process ensures that your hands are protected while still allowing the nail technician to access your nails.
Protective Clothing: Clothing can provide different levels of protection from UV rays. When visiting a nail salon, consider wearing long-sleeved shirts and long pants to cover your arms and legs. Additionally, don't forget to protect your face with sunglasses and a hat that covers your head and face.
Avoid Peak Sun Hours: While this may not directly impact your exposure during a manicure, it is important to be mindful of the sun's strongest rays when spending time outdoors. Try to avoid direct sunlight between 10 am and 4 pm, as the sun's UV rays are most intense during this period and can cause the most damage to your skin.
Choose LED Lamps: If you have the option, opt for salons that use LED lamps instead of UV lamps. While both types of lamps emit UV radiation, LED lamps generally emit lower levels of radiation.
Be Mindful of Exposure Time: Nail salon customers are typically exposed to UV lamps for a brief period, just enough to dry the nail polish. However, repeated and prolonged exposure to UV radiation over time can increase potential risks. Be mindful of the duration of your manicure sessions and try not to exceed the standard exposure time.

Research and studies
A 2014 study in JAMA Dermatology found that the level of UVA exposure from a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer. This study also noted that both UV and LED lamps emit ultraviolet radiation, mainly in the form of UVA rays. The American Academy of Dermatology supports this claim.
However, the interpretation of research results in this area can be challenging due to the lack of standardised regulations and specific requirements regarding the power of UV/LED lamps and the wavelengths generated for different nail products. The parameters of lamps can vary between manufacturers, and sellers may not provide clear usage instructions for specific products.
A study by researchers at Georgia Regents University in Augusta, GA, tested 17 light units from 16 salons. They found that higher-wattage UV lamps emitted more ultraviolet radiation, but the overall exposure time during manicures was brief.
Another study found that squamous cell cancer (SCC) was linked to three cases after exposure to UV nail lamps, with a time gap of 11 to 15 years between exposure and diagnosis. However, SCC was confined to specific areas of the hands and fingers, and no other photo-exposed regions showed signs of sun damage.
A survey by Bollard et al. found that 72% of respondents believed that UV nail lamps posed a cancer risk, and 82% said they would avoid gel manicures if there was a known risk.
While the research suggests a low risk of cancer from gel nail UV lights, it is important to note that any form of repeated UV radiation exposure could potentially have carcinogenic effects. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to the hands 20 minutes before UV light exposure during manicures as a precaution.

Alternatives to UV light drying
While the connection between nail salon UV lamps and cancer is not strong, UV light exposure can increase the risk of skin cancer and cause premature skin ageing. To avoid this, there are several alternatives to UV light drying for gel nails.
Firstly, you can use non-UV gel nail polishes, which are specially formulated to air-dry without the need for a UV or LED lamp. Examples of non-UV gel nail polishes include Sally Hansen's Miracle Gel line and Essie's Gel Couture line. These polishes are applied like regular nail polish and provide a similar look and durability to gel manicures. However, they may take longer to dry, just like traditional nail polish. To speed up the drying process, apply thin, even coats and use a quick-dry nail polish spray or submerge your nails in ice water after painting.
Another alternative is to use a gel alternative kit, such as Dazzle Dry, which air-dries in five minutes without the need for a UV lamp. Additionally, you can apply a broad-spectrum (UVA/UVB) sunscreen to your hands before exposure to UV light during manicures, although this does not protect against subungual squamous cell carcinoma.
It is important to note that LED lamps also emit UV radiation, predominantly in the form of UVA rays, so they are not a safe alternative to UV lamps in terms of cancer risk. However, LED lamps can cure gel polish as quickly and effectively as UV lights.
