Abstract

A method too permanently remove unwanted hair using a diode or other laser source in a post-treatment mode is disclosed. The method is not limited by skin pigmentation, causes no pain, and minimizes damage to surrounding tissue. The hair in the treatment area is first removed using conventional stripping techniques leaving the hair follicles substantially empty. While the follicles are still open, a special photosensitizing lotion is rubbed into the skin and then penetrates in the depth of the follicle. A solvent is then used to clean the surface of the skin from excess photosensitizer, while the photosensitizer remains in the follicles. In this way, the follicular ducts are selectively sensitized. An area containing the follicles is then irradiated by a diode laser in the near IR range and the follicles are thereby killed. There is no waiting time necessary in between different steps of treatment and generally only one application of laser radiation is required. The photosensitizer of the present invention may operate through photochemical or photothermal action.
