Make unwanted facial and body hair a thing of the past. No more painful waxing, electrolysis or razors! Laser hair removal is a procedure that uses an intense, pulsating laser to remove unwanted hair. As the laser passes through your skin, its heat damages the hair follicle, slowing future hair growth. While laser hair removal is highly effective at treating unwanted hair, you will generally need several treatment sessions before you can experience long-term results.
