What does spraying liquid nitrogen and using a certain light on skin actually do?|||As it is understood, liquid nitrogen freezing of some lesions of delicate skin, is quite safe and elegant in results, (even scars can be erased) if performed by a certified dermatologist.....the liquid nitrogen is applied directly over the lesion to be excised, and the depth is determined by the time the cotton swab impregnated with the nitrogen stays in the lesion....(seconds to 2 minutes, depending on the depth)
It is known that the tissue touched by the nitrogen freezes and dies, falling off without leaving a scar (if applied by physician)
Certain light?...could be laser beam, woods light, who knows?
Your doctor can tell you the specifics and we can comment after that....
