ABSTRACT:
A method of permanent hair removal which uses a high energy light source projected at the skin to cause death of the hair follicle by photothermolysis. The process uses either incoherent or coherent light energy. Additional melanin is added to the skin by a process which delivers the melanin to the region of the hair follicle thereby enhancing that area as a light absorbing target. Collateral damage to the surrounding skin tissue is minimized. The delivery process uses liposomes selected particularly to encapsulate and carry melanin to the target region. The invention also encompasses a general method of deleterious tissue destruction by selective introduction of melanin and subsequent photothermolysis.
