ALC has been using lasers for hair removal since 1996, when the first laser was FDA cleared for use on the public. Prior to the introduction of lasers for hair removal, electrolysis was the only form of long term or permanent hair removal. Electrolysis is a tedious, invasive, and painful process that involves inserting a needle into each hair follicle and delivering an electrical charge to destroy them one at a time. Electrolysis often requires years of treatments at regular intervals. Laser non-invasively treats hundreds of hair follicles simultaneously. So, in a few minutes, lasers can effectively treat an area that would take over an hour with electrolysis.
