Laser hair removal is based on a well-established scientific principle called selective photothermolysis. The laser emits light at a specific wavelength that is preferentially absorbed by melanin, the pigment found in hair. When this light is absorbed, it is converted into heat, which damages the hair follicle responsible for growth while largely sparing the surrounding skin. Modern devices are designed to deliver this heat in very short pulses, allowing the hair follicle to be targeted before the heat spreads to nearby tissue. Cooling systems built into the lasers further protect the skin’s surface, reducing the risk of burns or irritation. This combination of precise wavelength selection, controlled timing, and skin cooling is what allows laser hair removal to effectively reduce hair growth while minimising damage to the skin.
