The popularity of gel manicures has raised concerns about the potential health risks associated with UV nail lamps. These lamps, used to cure and harden gel nail polish, emit ultraviolet radiation, primarily in the form of UVA rays, which have been linked to premature skin ageing, wrinkles, sun spots and skin cancer. While the American Academy of Dermatology and the Skin Cancer Foundation consider the risk of cancer to be low, new research suggests that UV light from nail lamps can damage DNA and cause mutations in human cells. As a result, some people may opt for LED lamps, which are supposed to be safer, or choose alternative manicure options.

LED nail lamps emit UV radiation
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, according to a 2014 study in JAMA Dermatology. However, it is still wise to be aware of the potential risks. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to the hands 20 minutes before UV light exposure to reduce the risk.
Additionally, the type of lamp used is not the only factor that determines the amount of UV exposure. The distance between the lamp and the hands, the intensity of the light, and the duration of exposure can also affect the level of UV radiation received. It is important to note that even with these considerations, the UV radiation from nail lamps can still contribute to the overall UV exposure and potential health risks.
While the risk of skin cancer from nail lamps is relatively low, there are still concerns about their potential impact on health. New research suggests that the UV light in nail lamps could be harmful, and studies have shown that cell viability decreases with longer exposure times. Furthermore, the risk of subungual (under the nail) squamous cell carcinoma, a rare but aggressive form of skin cancer, is not mitigated by the use of sunscreen. Therefore, it is important to be informed about the potential risks associated with UV exposure from nail lamps and take appropriate precautions to protect the skin.

Potential health risks of UV radiation
The use of UV nail lamps has raised concerns about potential health risks due to UV radiation exposure. While LED lamps are often considered safer, it is important to note that both UV and LED lamps emit ultraviolet radiation, predominantly in the form of UVA rays. Here are some potential health risks associated with UV radiation from nail lamps:
Skin Cancer Risk: One of the primary concerns with UV nail lamps is the risk of developing skin cancer. UVA rays, the type predominantly emitted by nail lamps, have been linked to skin cancer. While the exposure time during a manicure is relatively short, regular and prolonged exposure over time may increase the risk. A 2014 study found that while the level of UVA exposure from gel manicures every two weeks may not significantly increase cancer risk, it is still a valid concern. Additionally, a 2013 study suggested that long-term exposure to UV nail lamps could potentially increase cancer risk and UV-induced skin aging.
DNA Damage and Cell Mutations: A recent study published in Nature Communications in 2023 found that radiation emitted by UV nail polish dryers can cause DNA damage and induce mutations in human cells. This discovery adds to the growing body of evidence suggesting potential adverse effects of UV nail lamp exposure.
Premature Skin Aging: In addition to cancer risks, UVA rays are associated with premature skin aging. Regular exposure to UV nail lamps may contribute to the development of wrinkles, sun spots, and other signs of aging. The intensity of UVA rays emitted by LED lamps, in particular, may accelerate this process.
Allergy Development: Aside from the concerns about UV radiation, there is also a chance of developing an allergy due to repeated exposure to gel nail polish. This is another factor to consider when assessing the potential health risks of gel manicures.
While the US Food and Drug Administration (FDA) has rated UV nail lamps as low risk, it is important to remember that the technology is relatively new, and the long-term effects may not be fully understood yet. To mitigate potential risks, some sources recommend applying sunscreen to the hands before UV light exposure or wearing fingerless gloves during manicures.

Skin cancer and premature ageing
While LED gel nail polishes are considered safer than UV nail lamps, they still emit ultraviolet radiation, predominantly in the form of UVA rays, which have been linked to premature skin ageing and skin cancer. A 2013 study found that long-term exposure to UV nail lamps may increase cancer risk and UV-induced skin ageing. Similarly, a 2014 study concluded that longer exposure times led to increased potential for skin damage, but the risk for developing cancer was small.
UVA rays are the most mutagenic wavelength range of the UV spectrum, penetrating the skin more deeply than UVB rays and playing a role in skin cancer development. They can also cause mutations in human cells. As such, the Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to hands 20 minutes before exposure to UV light during manicures.
However, this precaution does not protect against subungual (under the nail) squamous cell carcinoma, a rare but potentially aggressive form of skin cancer. While the risk of developing cancer from nail lamps is considered small, it is still a potential issue, and the full impact may not be clear for decades as gel manicures are a relatively new phenomenon.
Additionally, the intensity of the UVA rays emitted by LED lamps can be much higher than those from regular UV lamps or even the sun, and the potential impact of this intense exposure is not yet fully understood.
Therefore, while LED gel nail polishes may be safer than UV alternatives in terms of UV exposure, they are not entirely risk-free, and precautions such as using sunscreen or wearing fingerless gloves during manicures are recommended to mitigate the potential risks of premature skin ageing and skin cancer.

Allergies from repeated exposure
While the potential health risks of UV nail lamps have been widely discussed, there is also a concern about developing allergies due to repeated exposure to gel nail polish.
Gel nail polishes require exposure to ultraviolet light to harden and cure. This means that individuals who regularly get gel manicures are repeatedly exposing their hands, nails, and cuticles to UV rays. While the primary concern with this exposure is the potential development of skin cancer and premature skin aging, there is also a risk of developing an allergy.
According to a user on Reddit, the bigger concern with gel nail polish is the possibility of becoming allergic to it through repeated exposure. This user's comment sparked a discussion, indicating that while the development of allergies due to gel nail polish may not be a widely known issue, it is a potential concern for some individuals.
It is important to note that the development of allergies from repeated exposure to gel nail polish may not be as common as the other risks associated with UV nail lamps, such as skin cancer and premature aging. However, it is still a valid concern, and more research is needed to fully understand the potential risks involved.
To mitigate the risks associated with UV nail lamps, some individuals opt for alternative manicure methods, such as press-ons, dip nails, or traditional nail polish. Additionally, using sunscreen on the hands before exposure to UV light is recommended by sources such as the Skin Cancer Foundation and the FDA to reduce the potential harm caused by UV radiation.

Safer alternatives to gel nail polish
While the convenience and longevity of gel manicures are appealing, there are valid concerns about the safety of the UV light used to cure the polish. The good news is that there are safer alternatives to gel nail polish that can provide similar results without the same risks. Here are some options to consider:
Regular Nail Polish
A basic manicure with regular nail polish is a safer alternative to gel nail polish as it does not require the use of UV light to cure the polish. Regular nail polish is also easier to remove than gel polish, reducing the risk of damage to your nails. While it may not last as long as gel polish, you can extend the life of your manicure by applying a fresh layer of top coat every other day.
Vinylux Nails
Vinylux is a trademarked product by CND that offers a long-wear polish system. It consists of an all-in-one base and colour coat and a top coat, both of which must be used together. According to the company, Vinylux can last an average of five days without chipping, which is shorter than gel manicures but still impressive.
Dazzle Dry
Dazzle Dry is a lacquer system that lasts longer than traditional polish or hybrids and does not need to be cured by lights or soaked off. It comes off just like regular polish, so most people won't even realize you're not using gel. The system includes a non-drying nail prep, a clear base coat, a coloured lacquer, and a film-forming top coat.
Green Flash
The Green Flash system from Manucurist is a gel alternative that provides 10 days of wear and easy, acetone-free removal. It only needs a one-minute soak to remove, which is much quicker and easier than traditional gel removal. The application process is similar to a traditional gel system, with a base coat, colour, and top coat, but it cures under an LED light.
Polygel
Polygel is a hybrid formula that combines the best of acrylic powder and clear gel powder. It offers longer wear than gel polish but may require more maintenance as you need to fill in the area of growth rather than starting fresh. Polygel kits are available for at-home use, providing a convenient option for those who prefer to do their nails themselves.
Shellac
Shellac is a hybrid of gel and regular polish that offers a high-gloss finish and can protect your nails for up to two weeks. However, it requires curing with a UV lamp, so it may not be the best option if you want to completely avoid UV exposure. Additionally, improper removal can damage your nails, so it's important to fully soak off the product instead of filing or scraping it.
Nail Wraps or Stickers
Nail wraps and stickers provide a long-lasting effect similar to gel nails but without the need for UV light curing or complicated removal processes. They are applied directly on top of the nail and secured in place, making them a convenient and safe alternative to gel manicures.
Remember, even if you opt for safer alternatives, it's always a good idea to protect your skin during manicures by using sunscreen or wearing fingerless gloves, especially when using LED or UV lamps.
