Before laser hair removal, the hair in the treatment area should be shaved (not waxed or plucked). You’ll also be given special goggles to protect your eyes from the laser beam.
The nurse will press a hand-held laser instrument to your skin. A cooling device on the tip of the instrument or a cool gel will be used to protect your skin.
When the laser is activated, the laser beam will pass through your skin to the tiny sacs (follicles) where hair growth originates. The intense heat from the laser beam damages the hair follicles, which inhibits hair growth. Some discomfort in the skin is possible, and you’ll likely feel a sensation of cold from the cooling device or gel.
Treating a small area, such as the upper lip, might take only a few minutes. Treating a larger area, such as the back, might take several hours.
