What Is Laser Hair Removal?

Laser hair removal is a cosmetic procedure to get rid of unwanted hair on any part of the body. It works effectively in removing unwanted hair from face, arms, leg, bikini line, underarms and other areas. Laser hair removal method employs highly concentrated beam of light to destroy hair follicles thereby destroying the hair eventually. The laser treatment is completely safe and works permanently. This is why it is one of the most sought-after procedures by both men and women alike.

How Does Laser Hair Removal Work? 

Laser beam can effectively target coarse as well as soft hair while leaving the surrounding skin area undamaged. The laser hair removal method works on the primary principle of selective photothermolysis (SPTL) which implies that a specific duration of pulse and matched wavelength is focused on the targeted area without damaging the surrounding skin.

Another principle used in laser treatment is based on the fact that light is absorbed by the dark objects while light objects usually reflect light. So when laser is directed on the target area, the skin pigment – melanin, gets heated up ensuring that the laser beam only effects the basal stem cells of hair follicles. This is why, hair colours such as brown, black, reddish-brown etc. can be easily removed by laser treatment as compared to white or strawberry blonde colour of hair.

Most patients will return to normal as soon as they are done with the procedure. You can expect to see a visible reduction in hair after the procedure.
