Topical anesthetic is applied 45 minutes prior to treatment to help with any discomfort. The procedure itself takes approximately 30 minutes. Redness may last for several hours to a few days, but should not be severe. To avoid any unwanted skin discoloration after treatment you should avoid direct sun exposure and wear SPF daily for at least 6 weeks. Several treatments (3-5) are recommended every 2-4 weeks. Skin improvements are most noticeable after a series of treatments.
