Skin Research Recover-E incorporates healing properties, anti-inflammatory agents, and antioxidant substances into a remarkable formula that has unique benefits during the sleep cycle. Recover-E utilizes three of the most potent and proven free radical scavengers, vitamin E, vitamin C, and beta carotene. Beta carotene is the most efficient single antioxidant known and because it is fat-soluble, it is able to work in tandem with vitamin E in the lipid membranes of the cell. Researchers estimate that a single molecule of vitamin E within a membrane is sufficient to protect 1,000 lipid molecules from free radical chain reaction! Normal to ultra dry.
