Why Nail Salons Are Using UV Nail Lamps

In salons, two types of UV nail lamps have been used, Traditional and LED. Using different types of bulbs, fluorescent tubes in traditional UV nail lamps and Light emitting diodes in LED style UV nail lamps, these lamps emit UV and thus quickly dry and harden UV curable artificial nail coatings.

Although Ultra-violet is divided into three categories, UVA, UVB and UVC, all of these defines a UV wavelengths found in sunlight but only small fraction in natural sunlight is useful to cure artificial nail coatings. UVA are emitted from UV nail bulbs with no amount of UVC. Very less amount of UVA is used to cure artificial nail coats as they are specially designed. The UVA band have different wavelength and not all of them are used in curing artificial curable nails. Nail product formulation determines which UVA wavelength can be used according to brands like nail booth. Sometime if UV nail lamp is not in accordance with what a particular nail product requires, over or under curing might occur. Correct curing occurs when UV curable nail coat is treated with correct UVA wavelength for specific time. If under cured, UV nail coatings can solidify which doesn’t mean they are cured properly and if over cured, then might result in service breakdown which can burn sensitive tissues of the nail bed. Proper curing is required to avoid any adverse reactions.

UV nail lamps are considered to be safe and are being used in salon for more than 30 years. In a study “Do UV Nail Lamps Emit Unsafe levels of Ultrviolet Light? Two UV lamps were tested and it was found that they contain UV wavelength less than that found in natural sunlight. Another study was done by Dr. Robert Sayre, inventor of the SPF rating system for sunscreen and his associate Dr. John Dowdy, found that the exposure from the use of UV nail lamps is almost equal to the permissible monthly UV exposure as defined by international standards. The traditional and LED style UV nail lamps, are not much different and safe to use.
