– LightSheer diode laser removes unwanted hair on the skin by moving a handpiece across the areas being treated. It emits a beam of highly focused light that is absorbed by the pigment (melanin) in the hair. The laser pulses for a fraction of a second to heat up the hair and significantly impair the ability of the follicle to re-grow. The procedure can treat numerous hair follicles simultaneously so it is appropriate for treating large areas quickly and effectively.
