I believe that every manicurist has been asked such a question: Will the nail lamp be blackened? Does regular exposure damage the skin? I heard that multiple shots of nail art can cause skin cancer. Is it true?

First, find out the main cause of sunburn. In fact, UV is the real culprit! So, how exactly does it hurt our skin? At present, ultraviolet rays can be divided into UVA (320-400 nm), UVB (280-320 nm), and UVC (100-280 nm) by wavelength. Among them, UVC (100-280 nm) is blocked by the ozone layer and can hardly reach the surface. Therefore, we generally say "sun protection" refers to preventing UVA and UVB in the sun from damaging the skin.
Performance after skin sunburn: Generally, the skin of the human body will immediately experience redness and itching after experiencing prolonged or high-intensity exposure. Long-term direct exposure to ultraviolet rays may even produce sunburn, and may cause skin photoaging and even cause skin cancer.
The working principle of various nail arts: During the process of making nail art, the function of nail art lamp is to cure UV gel.
Nail lamps commonly used in the market are UV lamps and LED lamps. What's the difference between them? Xiaobian to give you a specific introduction ~ UV lamp is short for ultraviolet lamp. Many dermatologists believe that nail UV lamps are harmful. Because the UV lamps commonly used in nails are hot cathode fluorescent lamps, it is UVA (long-wave ultraviolet). Long-wave ultraviolet rays can reach deep in the dermis and cause melanin deposits on the skin, making the skin black and dry!
But Massachusetts General Hospital did a study on this: calculating the carcinogenicity of nail lamps by measuring the UV dose emitted by the nail lamps. They used three models of nail UV lamps, and after comparing with FDA-approved UV treatments commonly used in dermatology, they concluded that it is safe to use nail lamps once a week for 250 consecutive years. . Unless we really live to be 250 years old ...
LED lights are just like ordinary lighting, and do not harm human skin and eyes. In comparison, LED lights are more energy-efficient than UV lights and shorten the lighting time, but the corresponding price is also slightly more expensive than UV lights. LED lamps do not cause melanin to precipitate on the skin; furthermore, LED lamps are not as hot as UV lamps and do not burn. UV + LED lamp is a new type of phototherapy lamp with long service life, low power, low heat, more stable UV source, stronger penetrating ability, and will not have much impact on the skin.
