Laser resurfacing is a technique used during laser surgery wherein molecular bonds of a material are dissolved by a laser. It is often used in a medical context, especially in dermatology, for the treatment of acne vulgaris, scars, and spider telangiectasias or "spider veins" — a symptom of ataxia telangiectasia.

It can be combined with liposuction when this is done to remove excess fat from the chin and jaw area. The skin may be wrinkled after fat is removed and laser resurfacing can help tighten and smooth it over the new contours.
