The link between UV exposure and skin cancer has been known for a very long time. We all are aware that UV rays are there in the sun’s rays and we must protect against it. However, do you know that UV light is used for some cosmetic treatments as well? UV light in our environment and UV light for any cosmetic process is known to increase our risk of skin cancer. You may be wondering where UV light is used in the beauty process. Let me explain. Be it simple cuticle care at home or getting creative manicures at the salon, pretty nails have always been popular. UV nail lamps are primarily used on nail polish or gels that require ultraviolet radiation to harden. The devices contain multiple bulbs which emit UV rays. 

Nails and hands are exposed to the radiation for 10 minutes per session for gel manicures. We usually change the nails every two weeks. However, a study published last month has cautioned against the use of ultraviolet nail polish dryers for gel manicures as it poses a long-term health risk including skin cancer. A study was conducted by researchers at the University of California San Diego. The study found that the UV light emitting from these devices leads to cell death and cancer-causing mutations in human cells. The UV  light used by the dryer has a longer wavelength, it penetrates deeper into the skin. This may result in causing wrinkles, dark spots, loss of elasticity, large open pores and dilated blood vessels. So, what does this mean? Are UV lights not safe? Should you cancel your upcoming gel appointment and never put gel nails ever again? Not necessarily Skin cancer doesn't happen overnight.  The risk depends on frequency. "If  it is done once in a while, it's probably not a big deal. 

Potentially repeated exposures over many years can lead to skin cancer on the nail, around the nail bed, around the fingers.  Example: If you do gel manicures from the time that you're 17 onward, that's a lot of UV exposure that you face over a lifetime. Even though you're exposed to UV light for a short amount of time, it is recommended to limit the number of gel manicures you do in a year. Going twice a month increases your risk of potential damage. However, there are some precautions that individuals can keep in mind the next time you decide to go in for a manicure, which includes:

1. Check the bulb strength of the device  

Salons have a variety of nail lamps. UV lamps with a higher wattage produce more radiation and are more dangerous. Request the manicurist to use a UV lamp with the lowest wattage i.e., 9-watt.  

2. Avoid weekly manicures   

Reducing your exposure to dryer lamps can help lower cancer risk. If you absolutely must get your nails done every week, try to avoid gel manicures where the lamp is essential to set the nail polish.  

3. Apply sunscreen before using the lamp  

Coating your hands with sunscreen that has an SPF value higher than 50 can help protect your skin from the damaging effects of UV radiation. Apply the cream right before putting on the nail polish. 

4. Wear fingerless gloves   

Protective gloves that do not have fingertips are a good option when it comes to limiting your UV exposure. These are made using fabric that has UV-protectant properties. However, it is vital to note that the UV protection strength of these gloves reduces with each wash. Replace them after a few washes.  

People who frequently get their nails done should be aware of the risks associated with UV nail dryers. You should either take the appropriate precautions for a manicure or reduce your frequency. 

Having pretty nails is not worth it if it is going to bring skin cancer along with it.
