Lasers can help people by delivering energy to a specific target, melanin in this case. When the laser hits the melanin, it converts the light energy into heat. The heat then destroys the melanin and the surrounding tissue.

The main advantage of laser hair removal is that it delivers more energy to the hair follicle than other methods like waxing or shaving. This means that it can remove more hair with fewer treatments.
