Laser hair removal is a non-invasive procedure that offers a long-lasting solution to unwanted hair. Hair removal lasers are specially designed to target hair follicles that are in the active growth phase and the laser sends high-frequency light energy to destroy the follicles. The science behind this is known as selective photothermolysis, a fancy way of saying what we just explained with the naked eye, we see the laser pulses as only a beam of light.
