HAIR REMOVAL BY SELECTIVE PHOTOTHERMOLYSIS WITH AN ALEXANDRITE LASER

摘要

This invention is a hair removal by using an Alexandrite laser (50) emitting energy between 0.2 joules to 40 joules per pulse to provide an energy fluence between 15 joules and 70 joules per centimeter square, and having a pulse duration of between 100 microseconds and 10 milliseconds. A scanner (57) may be used to direct the laser beam on the tissue (60). The skin in the area to be irradiated may be shaved prior to exposure to laser treatment, and may be also covered by a protective substance serving as a heat sink (42).
