The Ruby Laser was one of the first lasers used in medicine. With recent advances in technology, this laser is now used to selectively destroy pigment in the skin without damaging the surrounding tissue or outer layer of the skin (epidermis). The Medlite laser (Q-swithched YAG) is complimentary to the Ruby, and is also used to remove professional, amateur, and traumatic tattoos, other pigmented lesions such as age spots and freckles, and some birthmarks. Another use is for temporary hair removal and the treatment of wrinkles without removing the skin (non-ablative resurfacing).
