标题 :Methods and compositions for enhancing collagen and proteoglycan synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

标 题 :Topical compositions for regulating the oily/shiny appearance of skin
发明人：BIEDERMANN KIMBERLY A; SCHUBERT HARRY L; PARRAN JR JOHN J
权利人:PROCTER & GAMBLE
摘要:The present invention relates to methods for inhibiting sebaceous gland activity in mammalian skin comprising administration of a topical composition comprising dehydroacetic acid or pharmaceutically acceptable salts thereof, and a dermatologically-acceptable carrier. The present invention also relates to methods and topical compositions further comprising agents which regulate the oily and/or shiny appearance of skin, and agents which treat acne and related skin disorders in mammalian skin and scalp. Methods of reducing sebum synthesis with the use of dehydroacetic acid, methods of regulating the oily and/or shiny appearance of skin, and methods of treating acne and other skin disorders are also encompassed by the present invention.

标题:Topical compositions
发明人：FLAVIN DANA
权利人:FLAVIN DANA
摘要:This invention provides compositions and methods of manufacturing such compositions that employ GRAS compounds which can act to promote the generation of stem, epidermal or other skin cells in the epidermis, activation of collagen synthesis, activation of hyaluronic acid synthesis, enhanced skin hydration, and dermal healing by stimulating stem cell and fibroblast migration to sites of needed repair. These compositions and methods are useful for rejuvenating the skin and for treating some skin-related aging or other dermal damaging conditions, including wrinkle reduction and treatment of minor dermal wounds.
