These professional peel facials give best results when received in a series of 3-5 treatments every 10 days to 2 weeks. These treatments include a skin analysis, cleanse and the correct peel for your skin followed by soothing oxygen to assist in healing and recovery. A specialty brightening, soothing or clearing mask follows. Retin-A and Tretinoin use are contraindicated and must not be used for 3 months prior to receiving professional peel treatments.
