标 题 :Methods and compositions for enhancing collagen, proteoglycan, and glutathione 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 or hydrolyzed whey protein; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid or a lipoic acid analogue or derivative. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

摘要:A cosmetic including two different systems for procurement of actives in the human skin and enhancing the collagen I synthesis. The cosmetic with enhanced collagen I synthesis can include 0.001 to 2% by weight, related to the total weight of the cosmetic, of a first retinol-containing system including retinol encapsulated in a chitosan and carboxymethyl cellulose shell, 0.001 to 3.5% by weight, related to the total weight of the cosmetic, of a second retinol-containing system including cationic liposomes composed of phospholipids and with a quaternary fatty acid monoamine with C 21 -C 23 alkyl residue and the difference to 100% by weight of cosmetic subsidiaries. Very small amounts of retinol in combination with both transport systems show a remarkable effect on the synthesis of collagen I in comparison with one or more other known combinations of retinol derivatives or encapsulated systems.

标题:Compositions for reducing UV-induced inhibition of collagen biosynthesis in human skin
发明人：FISHER GARY J; VOORHEES JOHN J
权利人:UNIV MICHIGAN
摘要:Exposure of human skin to ultraviolet (UV) radiation from the sun not only induces the production of enzymes (matrix metalloproteinases) that degrade collagen, but also inhibits the synthesis of new collagen by inhibiting the synthesis of procollagen. This UV-induced inhibition of the synthesis of collagen can be prevented by the topical application of a retinoid or c-JUN inhibitor to the skin prior to exposure to UV radiation.

权利人:DIOR CHRISTIAN PARFUMS
摘要:The invention concerns a dermatological or cosmetological composition, characterised in that it contains at least a compound capable of activating HSP 32 endogenetic synthesis or a functional peptide fragment of such a protein with pharmaceutically and/or cosmetologically acceptable carriers. The invention also concerns the use of a compound selected from the group consisting of procyanidolic oligomers (PCO) and their derivatives, caffeic acid esters and their derivatives and mixtures of said compounds, for preparing a composition designed to activate endogenetic synthesis of HSP 32 or a functional peptide fragment of such a protein.
