How Does Laser Hair Removal Work Science

Laser hair removal is based on the theory of selective photothermolysis.

How does laser hair removal work science. The light energy is converted to heat which damages the tube shaped sacs within the skin hair follicles that produce hairs. We use specific wavelengths of light that target pigment so the skin remains undamaged but the follicle is destroyed. We destroy the follicles by using pulses of light designed to heat the hair follicle to the point that it dies. Ipl which stands for intense pulsed light and laser hair removal are both long term and potentially permanent methods of hair reduction.

Laser hair removal is one of the most commonly done cosmetic. How does laser hair removal work. Laser hair removal is a medical procedure that uses a concentrated beam of light laser to remove unwanted hair. During laser hair removal a laser emits a light that is absorbed by the pigment melanin in the hair.

If you re not happy with shaving tweezing or waxing to remove unwanted hair laser hair removal may be an option worth considering. 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. Laser hair removal works by using concentrated light to affect hair follicles which are small cavities in the skin from which hair grows. The hair follicle absorbs the laser which is attracted to.

The laser energy destroys the follicle with the heat that it generates. To do this effectively it s important to be as close to your baseline skin color as possible says dr. The laser beam passes through the skin and is absorbed in the hair follicle residing underneath the skin s surface. This theory was developed from the clinical work showing that the hair follicle can selectively absorb energy sufficiently to disable it without causing damage to the surrounding tissue.
