Alpha-Hydroxy Acids (AHA) - the naturally occurring weak fruit and food acids - are a recent development in the skin care industry. They show excellent results in improving the collagen creation in muculuce layers and in the exfoliation of epidermis dead cells. The AHA's include glycolic, lactic, citric, malic and tartaric acids. Glycolic acid is present in sugar cane, lactic acid in sour milk, citric acid in fruits, malic acid in apples, and tartaric aced in grapes. Use and effectiveness of the acids was well known by ancient and folk medicine. Ancient youth remedies, such as milk baths to smooth the skin or stale wine application to the face to diminish the wrinkles, are well described. The widely used gylcolic acid has the smallest molecular size of any of the AHA and is believed to have the best penetration ability into the skin. Our products with alpha hydroxy acids also incorporate another important development in modern skin care; the use of atomized oxygen as a penetrative vehicle for Vitamin A Pamitate. Once the Vitamin A Pamitate penetrates the skin, it is converted to weak retinoic acid by the body's natural biochemical processes. This conversion is well documented by Hoffman-LaRoche in Switzerland, which manufactures the retinioc acid ingredient used to make Retin-A creams. This group of products containing alpha-hydroxy acids does not replace our home care regimen or the monthly salon visits. It complements our existing extensive product line making it more complete and competitive. We are confident you will benefit from the excellent quality and effectiveness of these products and our competitive prices.
