Immediately after the treatment, it is common to feel a mild sunburn-like sensation around the treatment site, which typically lasts 2-24 hours. Redness and/or swelling may accompany this and usually resolves in 2-3 days. Avoid sun exposure on the treated area and use a sunscreen SPF 45 or greater at all times throughout the course of treatment. The pigment may initially look raised/darker with a reddened perimeter. The pigment will gradually turn darker over the next few days and begin crusting and eventually flaking off of the skin from day 7-21. The vessels may undergo immediate graying or blanching, or they may exhibit a slight purple or red color change. The vessels will fully or partially fade in about 10-14 days.
