Enzyme treatments work by dissolving the cellular debris on the surface of the skin for a fresher, brighter appearance. Enzyme treatments produce results similar to a light chemical peel, but no layers of skin are removed, which prevents the skin from becoming thin, dry and aged. Enzyme treatments by Circadia all use a combination of natural enzymes including bromelain (found in pineapples), papin (found in papayas), and trypsin. These treatments are most effective when performed every 2 weeks.
