UV nail lamps emit UVA rays, which are linked to premature skin ageing and skin cancer
The use of UV nail lamps in gel manicures has come under scrutiny due to the potential risks associated with UV radiation exposure. These lamps are used to speed-dry regular manicures and are essential for setting gel manicures. While some salons use UV nail lamps, others employ LED lamps, which emit more intense UVA rays in a shorter duration.
UV nail lamps predominantly produce UVA rays, a type of ultraviolet radiation. Research has established a link between UVA ray exposure and premature skin ageing and an increased risk of skin cancer. A study by the University of California, San Diego, and the University of Pittsburgh used cell lines from humans and mice to test the impact of UV-emitting devices. The results indicated that chronic use of these devices could damage DNA and cause mutations in human cells, elevating the likelihood of skin cancer.
The concern with gel manicures is the cumulative effect of UV exposure over time. While a single session under a UV nail lamp may only last for 30 seconds to a few minutes, the repeated exposure associated with regular gel manicures can add up, increasing the potential for harm. This is particularly true for nail salon equipment, which often emits more potent UV radiation than the devices used in laboratory studies.
The potential risks associated with UV nail lamps have sparked safety concerns among dermatologists and patrons alike. Some individuals opt for LED devices, believing they minimise UV light exposure. However, it is important to note that while LED lamps may have shorter curing times, they emit more intense UVA rays. As a precaution, the Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to the hands before undergoing a gel manicure.

The use of UV nail dryers can cause DNA damage and mutate cells
The concern is that the regular use of UV nail dryers over time could increase the risk of skin cancer, specifically squamous cell carcinoma. While gel manicures are relatively new, DNA damage from UV exposure can take time to build up, and it is possible that more skin cancer cases associated with UV nail dryers will emerge in the coming years. The study also found that LED lamps, which are often used to cure gel polish, emit more intense UVA rays than regular UV lamps or even the sun, raising further concerns about the potential health risks of these devices.
It is important to note that the link between UV nail dryers and skin cancer is not yet conclusive, and more research is needed to accurately quantify the risk. However, the potential for DNA damage and cell mutation is a serious concern. UV radiation has also been linked to premature skin aging and sunspots, and it is recommended that people who regularly use gel nail polish with UV dryers monitor their skin for any changes and consult a dermatologist if they have any concerns.
While the use of UV nail dryers may pose some risks, there are precautions that can be taken to mitigate these risks. The Skin Cancer Foundation recommends applying a broad-spectrum (UVA/UVB) sunscreen to hands before UV light exposure. Additionally, some people choose to wear UV gloves or use alternative methods for drying nail polish, such as quick-dry top coats or LED lamps that do not emit UV radiation.
The potential risks associated with UV nail dryers have sparked concerns among customers and nail technicians alike. Some people may choose to avoid gel manicures altogether or opt for alternative nail treatments that do not require UV light exposure, such as regular polish with a quick-dry top coat. It is essential to weigh the risks and benefits and make an informed decision about the use of UV nail dryers.

LED nail lamps are also known to emit UV radiation, despite being marketed as a safer alternative
LED nail lamps are often marketed as a safer alternative to UV nail lamps. However, it is important to note that LED lamps also emit UV radiation, predominantly in the form of UVA rays. According to Dr. Chris Adigun, a dermatologist who contributed expert advice on the safety of gel manicures for the American Academy of Dermatology, the belief that LED devices skip or minimise ultraviolet light exposure is a "big misnomer".
The intensity of the UV radiation emitted by LED lamps is a cause for concern. While LED lamps have shorter curing times than regular UV lamps, this is because the UVA rays they emit are much more intense. Dr. Adigun notes that the UVA rays emitted by LED lamps are more intense than those emitted by regular UV lamps or even the sun. This raises worries about the risk of skin cancer, as hands, cuticles, and nails are exposed to these intense UV rays during the gel manicure process.
The potential harm caused by LED nail lamps was highlighted in a 2023 study published in Nature Communications. The study found that exposure to a UV nail polish dryer, including LED lamps, can lead to cell death, damage, and DNA mutations in human cells. Specifically, the study exposed three different cell lines to a UV nail polish dryer and observed cell death, damage, and DNA mutations after both acute and chronic exposure. These findings suggest that the radiation emitted by UV-nail polish dryers, including LED lamps, may pose a risk to human health.
While the potential risks associated with LED nail lamps are concerning, it is important to consider the level of exposure. A 2014 study in JAMA Dermatology found that the level of UVA exposure associated with a gel manicure every two weeks is probably not high enough to significantly increase the risk of skin cancer. However, it is still crucial to be aware of the potential risks and take precautions when using LED nail lamps. Applying a broad-spectrum (UVA/UVB) sunscreen to the hands before exposure to UV light during a gel manicure can help mitigate the risks associated with UV radiation exposure.

The risk of developing melanoma under the nail is a concern, as it can cost you the entire nail bed, or even your life
The UV lamps used to cure gel manicures emit UVA rays, which are known to increase the risk of skin cancer. While the direct sun equivalent of the UV exposure from a gel manicure is low, the risk of skin cancer is still present, especially with repeated exposure over time. This risk is not limited to the skin, as skin cancer can develop under the nail plate as well.
Melanoma of the nail unit, also known as subungual melanoma, is a rare but serious form of skin cancer that can develop under the nail. It often starts as a narrow pigmented band visible on a single nail plate and can lead to nail dystrophy, or thinning, cracking, or distortion of the nail plate. In some cases, melanoma of the nail unit may present as a mass under the nail plate, lifting it (onycholysis), or looking like a wart (verrucous).
The risk of developing melanoma under the nail is a significant concern as it can have severe consequences. If left untreated, melanoma can spread to other parts of the body and become life-threatening. Even with treatment, delays in diagnosis can lead to poorer outcomes, potentially resulting in the loss of the entire nail bed or finger.
Therefore, it is crucial to be vigilant about any changes to your nails and consult a doctor if you notice any suspicious spots or marks. While gel manicures may enhance the appearance of your nails, it is important to weigh the risks involved and consider alternative options, such as regular polish with a quick-dry top coat, to minimize UV exposure and reduce the potential for nail damage and health risks.

Gel manicures can also cause allergies, which may develop into lifelong allergies to acrylics
The popularity of gel manicures has led to a rise in reported cases of allergic reactions. These allergic reactions can be severe and may even be life-changing. The main culprit behind these allergies is a chemical called methacrylate, which is found in gel polishes. When the gel polish doesn't cure accurately or sufficiently, the skin can become sensitised to the chemicals, leading to allergic contact dermatitis. This type of reaction is lifelong due to the skin's memory.
The risk of developing an allergy increases if the gel touches your skin during the application process. It is important to note that even a small amount of gel polish coming into contact with the skin can trigger an allergic reaction. This can lead to a range of symptoms, including swelling, eczema, and redness around the nails. The reaction may also spread to other areas of the body, such as the eyes and neck, if the chemical has been in direct contact with those areas.
To lower the risk of an allergic reaction, it is recommended to only get manicures from professional technicians. Dr Wedgeworth also advises avoiding manicures if you have damaged skin or if you have recently trimmed your cuticles extensively. Additionally, reducing the frequency of gel manicures can help lower the risk.
The British Association of Dermatologists (BAD) has expressed concern about the allergy epidemic associated with gel manicures. They conducted a study that found 2.4% of people who used gel polishes had an allergy to the chemicals used. The consequences of these allergies can be severe, including nails loosening or falling off, severe rashes on the face, neck, and upper chest, difficulty breathing, and worsened asthma.
