Which cosmetic procedure is used to remove unwanted hair?

Electrolysis is a cosmetic procedure specifically designed to remove unwanted hair. It works by using electric current to destroy hair follicles, which prevents future hair growth in the treated areas. This method is effective for all hair types and colors and is one of the few methods that is approved by the FDA for permanent hair removal.

Other procedures in the options, such as microdermabrasion, laser skin resurfacing, and facial peeling, serve different purposes. Microdermabrasion is a technique for exfoliating the skin to improve texture and reduce the appearance of scars and fine lines. Laser skin resurfacing focuses on improving skin quality by targeting wrinkles, age spots, and scars through the use of concentrated light beams. Facial peeling involves the application of chemical solutions to exfoliate the skin deeply, addressing issues like pigmentation and acne. None of these procedures specifically target hair removal like electrolysis does. Thus, electrolysis is the correct choice as it directly addresses the removal of unwanted hair.
