Laser hair removal is a cosmetic procedure that uses concentrated light (laser) technology to remove unwanted hair. During the process, a laser emits a light absorbed by the pigment (melanin) in the hair. This light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs.
Laser hair expulsion is a corrective technique that utilizes a strong laser or serious beat light (IPL) to eliminate undesirable hair. This light source warms and annihilates hair follicles in the skin, which upsets hair development.
