• introducing lazer hair removal ,another process of removing unwanted hair by means of "exposure to pulses of laser  light that destroy the hair follicle" . It had been performed experimentally for about twenty years before becoming commercially available in the mid Skin irritation. Temporary discomfort, redness and swelling are possible after laser hair removal. Any signs and symptoms typically disappear within several hours.

During laser hair removal, a laser beam passes through the skin to the  hair follicle. The intense heat of the laser damages the hair follicle, which inhibits future hair growth. Laser hair removal is most effective for people who have light skin and dark hair.

Although laser hair removal  slows hair growth, it doesn't guarantee permanent hair removal. It  takes multiple laser hair removal treatments to provide an extended hair-free period. Periodic maintenance treatments might be needed as well.I personally think that this process does damages to your skin because when the hair follicles are being destroyed some pigments in your skin are also being done too. yes it gets the job done but it also gets rid of hair you may actually need to protect your skin from stuff like germs ,diseases etc.
