Ask the Expert: Are the UV Lamps in the Dryers at the Nail Salon Safe to Use? (2024)

By Skin Cancer Foundation • January 23, 2023

Lamps that emit ultraviolet (UV) radiation have become a standard at many nail salons, causing patrons to wonder about skin cancer risks while getting a manicure. These lamps are typically used to speed-dry regular manicures, and they are requiredto set gel manicures. Some nail lamps are called “UV” lamps, and some are called LED lamps, butbothemit UV radiation. They predominantly produce UVA rays, which have been linked to both premature skin aging and skin cancer.However, even the most intense of these devices presents only a moderate UV risk — a far lower risk than that presented by UV tanning devices.

What you can do: To play it safe with gel manicures, The Skin Cancer Foundation recommends applying a broad spectrum (UVA/UVB) sunscreen to hands 20 minutes before your hands are exposed to UV light. However, even this precaution does not protect against subungual (under the nail) squamous cell carcinoma, a rare but potentially aggressive form of skin cancer. If getting a regular manicure, the safest bet is to allow nails to air-dry naturally, avoiding the drying lamps altogether or use an air blower or fan without UV lights.

Now, let's delve into the concepts mentioned in the article about the skin cancer risks associated with UV lamps in nail salons. These lamps, whether labeled as "UV" or "LED," emit ultraviolet (UV) radiation, primarily in the form of UVA rays. Here's a breakdown of the key points:

1. UV Lamps in Nail Salons:

   • These lamps are commonly used for speeding up the drying process of regular manicures.
   • They are required for setting gel manicures, providing a durable finish.

2. UV Radiation Risk:

   • Both UV and LED lamps emit UV radiation, with a predominance of UVA rays.
   • UVA rays have been linked to premature skin aging and an increased risk of skin cancer.

3. Comparison to UV Tanning Devices:

   • Despite emitting UV radiation, nail lamps present only a moderate UV risk.
   • The risk associated with these devices is significantly lower than that posed by UV tanning devices.

4. Protective Measures:

   • The Skin Cancer Foundation recommends applying broad-spectrum (UVA/UVB) sunscreen to hands 20 minutes before exposure to UV light during gel manicures.
   • Even with sunscreen, there is no complete protection against subungual (under the nail) squamous cell carcinoma, a rare but potentially aggressive form of skin cancer.

5. Safer Options for Regular Manicures:

   • To minimize UV exposure, it is suggested to allow nails to air-dry naturally during regular manicures.
   • Alternatively, the use of an air blower or fan without UV lights can be a safer option.

It's crucial for individuals visiting nail salons to be aware of these risks and take necessary precautions, especially if opting for gel manicures. As an expert in dermatology, I emphasize the importance of skin protection and informed decision-making in the pursuit of beauty and self-care.
