The number of sessions of AviClear needed to see results depends on the severity and extent of your acne. Each session lasts about 30 minutes. Most patients see a significant improvement after just one session. For best results, the treatment should be performed once a month for a total of three months, depending on how your skin responds. In addition, AviClear can be paired with other laser resurfacing treatments to reduce the appearance of old acne scarring.
