Abstract
An ascorbic acid-based composition and related method for the treatment of aging, photo-damaged or inflamed skin is disclosed. The composition includes water and ascorbic acid, at least a portion of which has generally been pretreated by being dissolved under relatively high temperature and concentration conditions. The composition typically includes at least about 5.0% (w/v) ascorbic acid formulated to have a pH above 3.5. 10 to 50% of the ascorbic acid is pretreated ascorbic acid. The composition may also include a non-toxic zinc salt, a tyrosine compound, and/or pharmaceutically acceptable carrier. The composition may include an anti-inflammatory compound, such as aminosugar and/or sulfur-containing anti-inflammatory compound. Embodiments containing an aminosugar such as glucosamine are further useful for treating rosacea and other inflammatory skin ailments. The composition may be administered in a variety of forms suitable for topical application on skin.
