| 摘要 |
The invention provides methods and compositions for improving and reducing age-related skin disorders, particularly fine lines and/or wrinkles, including fine wrinkles, on human skin. The cosmetic compositions of the invention are formulated with less than effective amounts of anti-wrinkle active agents (e.g., drugs) or are devoid of such active agents, which include alpha -hydroxy acid and derivatives and salts thereof, tretinoin and derivatives and salts thereof, or vitamin C, and which are typically used for treating and reducing skin lines and/or wrinkles. As tested in clinical trials, the compositions of the invention reduced and improved fine lines and/or wrinkles as well as, or better than, preparations containing alpha -hydroxy acids, alpha -hydroxy acid salts, tretinoin, or vitamin C, thereby achieving effective anti-wrinkle formulations that are safe, economical and stable, without potential adverse effects to the user that can accompany the use of the aforementioned, typically-employed antiwrinkle preparations and products. |
