The laser machine is the only one with good therapeutic result in short time. Laser hair removal works by targeting the pigment inside the hair follicle with very little damage to the delicate pores and structures of the skin. Because hair cycles through "growth" and "dormant" phases, and because during the "dormant" phase the follicle has no pigment, at least 6-8 treatments will be needed. The number of sessions will vary for each individual.

A laser treats any "active" follicle, even if the hair has not yet reached the surface of the skin, or if the hair shaft is not straight. While some areas of the body are more sensitive than others, most patients report little or no discomfort. For more sensitive patients, anesthetic creams or ice can be applied prior to the treatment.
