Thank you for this question. You need to remember that the UV spectrum is falls in the 100 – 400nm range… the shorter the wavelength, the more “aggressive” it is on your skin. The UV lamps used for curing nails sits to the very highest side of the UV spectrum, and generally these are LED’s, so you cannot be burnt with these. Furthermore, the amount of time spent under a curing LED lamp is very limited. So getting skin cancer from having your nails done is really not at all likely.
