Ipl which stands for intense pulsed light and laser hair removal are both long term and potentially permanent methods of hair reduction. We destroy the follicles by using pulses of light designed to heat the hair follicle to the point that it dies. The laser energy destroys the follicle with the heat that it generates.

The laser beam passes through the skin and is absorbed in the hair follicle residing underneath the skin s surface. They involve using a beam of light over the skin which targets areas of high pigmentation heating them to the point of destruction of the hair follicle. Destroyed hairs are then either dissolved within the skin or rejected by the body within two to three weeks.

The light energy is converted to heat which damages the tube shaped sacs within the skin hair follicles that produce hairs. How does laser hair removal work. Laser hair removal is based on the theory of selective photothermolysis.
