MODEL RELEASED. Laser hair removal. Woman having Plasmalite laser cosmetic treatment to remove unwanted hair from her face. She is wearing goggles to protect her eyes from damage by the laser. Plasmalite technology uses pulses of light focused through a handset by an operator onto the surface of the skin. The light causes the hair shaft and follicle to heat up, and eventually the follicle dies and the hair cannot regrow. Several treatments may be needed to remove hairs from a region entirely.
