If you are fed up with shaving, waxing, or tweezing, laser hair removal can be a perfect option for you. Laser hair removal is one of the most common cosmetic procedures. In laser hair removal, a concentrated beam of light which is known as Laser is used to remove unwanted hairs.

During the procedure, the laser emits a beam of light which is absorbed by melanin or pigment in the hair follicles. The light energy then is converted into heat energy which destroys the tube shapes sacs within hair follicles which produce hairs. Laser hair removal is one of the best ways to get rid of unwanted hairs. In minutes, it destroys hair follicles with minimal discomfort. Laser hair removal works best for the people who have a fair complexion and dark hairs however people without this combination can also get great results with the treatment. The basic principle behind hair color and skin type is that the pigment of hairs should absorb the light not the pigment of the skin.

But now with the help of advanced technology laser hair removal has also become an option for people with darker skin.
