Lasers are useful for removing unwanted hair from the face, leg, arm, underarm, and bikini line as well as other areas where unsightly hair is a problem. Through advanced laser technology, clients can experience superior hair reduction results safely and effectively. The primary principle behind laser hair removal is selective photothermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers can cause localized damage by selectively heating dark target matter, melanin, in the area that causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects, so laser energy can be absorbed by dark material in the skin, but with much more speed and intensity. Laser hair removal has the following benefits Precision – lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged. Speed – each pulse of the laser takes a fraction of a second and can treat many hairs at the same time. The laser can treat an area approximately the size of a quarter every second. Predictability – most patients have permanent hair loss after an average of three to seven sessions.
