Laser hair removal involves using a laser to heat the small cavities in the skin (follicles) that the hair grows out of. This damages the follicles, which prevents hair growing.

Each treatment may take between 15 minutes to over an hour. Your eyes must be protected with specially designed goggles during the procedure, and you may experience some pain. The area may be red with a raised rash for up to 24 hours afterwards.
The number of treatments needed depends on the area to be treated and the system that’s used.
