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 :use of an extract of a non-photosynthetic filamentous bacterium as an agent for enhancing the endogenous synthesis of superoxide dismutase
发明人：MAHE YANN; MEYBECK ALAIN
权利人:OREAL
摘要:Promoting endogenous production of superoxide dismutase (SOD) comprises the use of an extract (I) of non-photosynthetic, non-fruiting filamentous bacteria in cosmetic, dermatological or pharmaceutical applications. Use of an extract (I) of non-photosynthetic, non-fruiting filamentous bacteria: (1) in a composition based on a cosmetic medium, as an agent for promoting endogenous production of superoxide dismutase (SOD); or (2) for production of a pharmaceutical or dermatological composition for promoting endogenous production of SOD. Independent claim are also included for: (1) a composition comprising a physiological medium containing Vitreoscilla filliformis extract (Ia) and lycopene (specifically at 0.000000001-0.1 wt. %) or a compound having catalase activity and/or a compound having peroxidase activity; and (2) cosmetic treatment methods for treating loss of firmness and/or elasticity of the skin or for treating skin exposed to sunlight, involving application of compositions containing (Ia).
