The light from gel nail lamps can damage DNA and cause cell mutations
The popularity of gel manicures has soared in recent years, but concerns have been raised about the potential health risks associated with the UV light used in the process. UV nail lamps are used to cure and dry gel nail polish, and this exposure to ultraviolet light, specifically UVA radiation, has been linked to DNA damage and cell mutations.
A study published in Nature Communications in 2023 found that the radiation emitted by UV nail dryers can damage DNA and cause permanent cell mutations. This damage can lead to potential long-term health consequences, including an increased risk of skin cancer and premature skin aging. The study also highlighted the lack of standardisation in the industry, with no set time limit for how long hands should be kept under the lamp, and the potential for over-curing.
UVA radiation is the most mutagenic wavelength range of the UV spectrum, penetrating the skin more deeply than UVB rays. This type of radiation is also associated with tanning beds and sunlight, and it is well-established that cumulative exposure to UV radiation is the biggest risk factor for non-melanoma skin cancer. While the FDA considers nail-curing lamps to be low-risk, the potential for harm exists, particularly with frequent and prolonged use.
To minimise the risk of DNA damage and cell mutations, it is recommended to limit the use of UV nail lamps and to space out manicures. Sunscreen with an SPF of at least 30 can also be applied to the hands before a manicure to provide some protection from UV exposure. Additionally, choosing alternative manicure options, such as regular nail polish or nail stickers, can help avoid the risks associated with UV light exposure during gel manicures.

UVA exposure is linked to skin cancer and premature aging
The light boxes used during gel manicures emit ultraviolet A (UVA) radiation, which is associated with a higher cancer risk. UVA radiation has been linked to several skin concerns, including premature skin aging and an increased risk of skin cancer.
UVA radiation is known to cause premature aging of the skin, such as wrinkles and sun spots. This is because UVA rays penetrate the skin more deeply than UVB rays, playing a significant role in skin cancer development and premature aging. The risk of premature aging is further increased when hands, cuticles, and nails are regularly exposed to UV rays, which can be more powerful than sunlight.
A study published in Nature Communications in 2023 found that radiation from UV nail dryers can damage DNA and cause permanent cell mutations. This adds to the growing concern that UV nail dryers may increase the risk of early-onset skin cancer. The study also highlighted the lack of regulation in the industry, with no standard for how long hands should be kept under the lamp, and the potential for over-curing.
While the FDA considers nail-curing lamps to be low-risk, it is important to be aware of the potential dangers and take precautions to protect your skin. This includes spacing out the time between manicures, limiting the amount of time under the lamp, and protecting your skin with sunscreen or UPF gloves. It is also recommended to inspect your nails for any abnormalities, such as dark vertical lines, which can be a symptom of melanoma, and to take a break from nail polish every couple of months.

The frequency of gel manicures and cumulative UV exposure increases the risk
The popularity of gel manicures has raised concerns about the potential health risks associated with the repeated exposure to ultraviolet (UV) light during the curing and drying process. While the use of UV nail lamps is a standard procedure in salons, the cumulative UV exposure from frequent gel manicures can increase the risk of skin damage and other adverse effects.
UV nail lamps emit ultraviolet A (UVA) radiation, which has been linked to various skin concerns. UVA rays are the most mutagenic wavelength range of the UV spectrum, penetrating the skin more deeply than UVB rays. This type of radiation is associated with a higher risk of skin cancer and premature skin aging, including the development of wrinkles and sun spots. The risk is particularly significant for individuals who start getting gel manicures at a young age, as they accumulate more lifetime exposure to UV light.
The frequency of gel manicure appointments can contribute to the cumulative UV exposure and increase the risk of adverse effects. With each gel manicure application, hands are typically placed under the UV lamp for up to a minute, and sometimes longer, to cure and dry the polish. While a single visit to the salon may only result in a few minutes of UV exposure, regular and frequent gel manicures can lead to significant cumulative UV exposure over time. This cumulative exposure increases the risk of DNA damage, cell mutations, and the development of skin cancer.
Additionally, certain medications and skincare products can increase sensitivity to UV light, making individuals more susceptible to blistering or burning during gel manicures. It is recommended that people taking specific medications, such as antibiotics, oral contraceptives, or cholesterol medications, exercise caution and consider alternative manicure options.
To minimize the risk associated with UV exposure during gel manicures, it is essential to take precautionary measures. Applying broad-spectrum sunscreen with an SPF of 30 or higher to the hands before the manicure can provide protection. Water-resistant sunscreen is advisable in case hand rinsing is required during the process. Wearing fingerless gloves with a high ultraviolet protection factor (UPF) can also reduce UV exposure, although sunscreen is still necessary to protect the exposed skin. Spacing out the time between manicures and limiting the duration of UV lamp use during each appointment can further reduce the cumulative UV exposure and associated risks.

LED lamps also emit UV radiation, despite marketing claims
Despite marketing claims, LED lamps do emit UV radiation. While some lamps are referred to as UV lamps and others as LED lamps, both emit ultraviolet radiation, predominantly in the form of UVA. According to Dr. Chris Adigun, a dermatologist in North Carolina, the belief that LED devices skip or minimise UV light is a "big misnomer". Adigun states that "gels, by definition, need UVA exposure to polymerise. So if there's no UVA, there is no gel manicure".
UVA rays are the most mutagenic wavelength range of the UV spectrum, penetrating the skin more deeply than UVB rays. They play a role in skin cancer development and premature skin ageing, such as wrinkles and sun spots. A 2023 study published in Nature Communications found that radiation from UV nail dryers can damage DNA and cause permanent cell mutations. The study's authors write that their findings "strongly suggest that radiation emitted by UV-nail polish dryers may cause cancers of the hand and that UV-nail polish dryers, similar to tanning beds, may increase the risk of early-onset skin cancer".
The American Academy of Dermatology has also weighed in on the issue, stating that both UV and LED lamps emit ultraviolet radiation, predominantly in the form of UVA. The FDA considers nail-curing lamps to be low-risk, but acknowledges the potential dangers. Dr. Wysong of the University of Nebraska Medical Center warns that "cumulative exposure to UV radiation over a lifetime is the biggest risk factor for non-melanoma skin cancer".
To protect your hands from UVA exposure during a gel manicure, you can wear sunscreen on your hands or fingerless gloves.

Sunscreen, gloves, and limiting exposure can reduce the risk of harm
The use of UV nail lamps in gel manicures has raised concerns about the safety of these devices and their impact on health. The lamps emit ultraviolet A (UVA) radiation, which is associated with an increased risk of skin cancer and premature skin ageing. While the level of exposure during the short time under the lamp for a single manicure is probably not high enough to significantly increase the risk of skin cancer, frequent visits to the salon for gel manicures can increase the risk.
To reduce the risk of harm, it is recommended to apply sunscreen to your hands before a gel manicure. The sunscreen should be broad-spectrum, covering both UVA and UVB light, with an SPF of 30 to 50. It is also important to ensure that the sunscreen is water-resistant, as you may need to rinse your hands during the manicure. Additionally, you can wear ultraviolet protection factor gloves, which are available as manicure-ready fingerless gloves with a UPF of 50.
It is also recommended to limit your exposure to UV light by spacing out the time between manicures and avoiding getting gel manicures too frequently. You can also consider taking a break from nail polish every once in a while, allowing your nails time to heal and giving you an opportunity to inspect them for any abnormalities.
By taking these precautions, you can help reduce the risk of harm associated with UV exposure during gel manicures and enjoy your manicure without worry.
