Prior to treatment, a topical anesthetic is applied to the skin. Due to the nonablative nature of the laser, however, most patients experience minimal discomfort. The ResurFX laser handpiece is run over the treatment area, while the temperature-monitoring CoolScan system protects the skin. Treatments take, on average, 30 minutes. Several treatments, spaced several weeks apart, usually produce the best results.
Patients can return to their normal activities immediately after ResurFX treatments; mild redness, tingling or swelling are usually the only side effects, and they subside within a few days.
