Abstract
An ascorbic acid (Vitamin C) composition in a nonaqueous or substantially anhydrous silicone vehicle has superior stability. Particulate ascorbic acid is substantially insoluble in the disclosed polyorganosiloxane vehicles, and the vehicle substantially excludes environmental oxygen. The ascorbic acid particles have surprisingly been found to have a high degree of bioavailability and effectiveness, for example in topical applications to reduce wrinkles and increase collagen growth and elasticity.
