Hair reduction treatments typically involve the use of laser or intense pulsed light (IPL) technology to target hair follicles, inhibiting their growth. These treatments are commonly used to achieve long-term hair reduction on various parts of the body, including the legs, underarms, bikini area, and face. The light energy is absorbed by the pigment in the hair follicles, damaging them and inhibiting future hair growth. Multiple sessions are usually required to achieve significant reduction, and results can be long-lasting, with many individuals experiencing months to years of smoother, less hairy skin.
