Laser Hair Removal All You Need To Know


Overview Laser hair removal is a procedure that uses focused beams of light to remove undesirable body hair.

During the procedure

Your doctor will press a handheld laser against your skin. Depending on the type of laser, a cooling device or gel can be used to protect your skin and reduce the risk of side effects.
