权利人:LVMH RECH
摘要:The invention relates to the use of an extract of the plant Potentilla erecta in the field of cosmetics and pharmacy, especially in dermatology. The invention more particularly relates to any application in which it is sought to reinforce the dermo-epidermal junction or to improve hair condition, by the improvement of the synthesis of collagen VII by keratinocytes and/or fibroblasts. In particular, these applications concern toning of the skin, diminishing of wrinkles or hair care. The invention also relates to a novel method of culture of cells, in particular of human fibroblasts or keratinocytes, for promoting the formation of collagen VII.

摘要:A method for disrupting epithelial barrier function in a host in need of the topical administration of a physiologically active substance which comprises applying to the epithelium of the host, barrier-disrupting amount of at least one agent selected from the group consisting of an inhibitor of ceramide synthesis, inhibitor of acylceramide synthesis, inhibitor of glucosylceramide synthesis, and inhibitor of sphingomyelin synthesis, an inhibitor of fatty acid synthesis, an inhibitor of cholesterol synthesis, a degradation enzyme of ceramides, acylceramide, glucosylceramides, sphingomyelin, an inhibitor of phospholipid, glycosphingolipid, including glucosylceramide, acylceramide or sphingomyelin degradation, and both inhibitors and stimulators of metabolic enzymes of free fatty acids, ceramide, and cholesterol, as well as a topical composition useful therefor are disclosed.

发明人：BONTE FREDERIC; DUMAS MARC; HEUSELE CATHERINE; LE BLAY JACQUES
权利人:LVMH RECH
摘要:The present invention relates to a method of cosmetic treatment for combating the effects of skin ageing and to novel cosmetic compositions which are particularly suitable for carrying it out. According to the invention, at least one agent for promoting the adhesion of the keratinocytes of the epidermal basal layer to the dermo-epidermal junction, especially to the collagen IV of said junction, such as, in particular, a divalent metal salt or complex, preferably magnesium aspartate or magnesium chloride, is used, optionally in association with a stimulant of collagen IV synthesis and/or a stimulant of collagen VII synthesis.
