The invention enables to provide care for sensitive skins, in particular to fight against skin sensitivity, uncomfortable reactions, to provide sensations of well-being, and to produce a local analgesic action.

Abstract: A dermatological or cosmetological composition for an external topical administration, included together with pharmaceutically and/or cosmetologically acceptable excipients: at least one UVA-stabilizing and/or UVB-stabilizing screening agent, at least one compound capable of activating the endogenous synthesis of Heat Shock Protein (HSP) 32 or a functional peptide fragment of such a protein, and forskolin or any extract containing it.

Abstract: The invention relates to uses in the cosmetic or pharmaceutical field of at least one active agent which increases the expression and/or the functionality of the. CD44 membrane receptors of skin cells and/or which improves the binding to the surface of the said skin cells of hyaluronic acid, and/or of collagen, in particular of collagen I and/or collagen IV, and/or fibronectin.

Abstract: The invention concerns the use of at least an oligosaccharide comprising 2 to 6 sugars and containing at least 2 galactose units, preferably 2 vicinal end-of-chain galactose motifs, or a plant extract containing same, as a cosmetic or dermatological agent, in particular for stimulating the beta-endorphin production in the skin.

Abstract: The invention relates to an ester. The ester is characterized in that it presents the following chemical formula (I): ##STR1## in which: R.sub.1, R.sub.2 and R.sub.3 independently represent an atom of hydrogen, a methyl radical,A represents the following groups: ##STR2## R.sub.4 and R.sub.5 are identical or different and each represents a chain of the form:--B.sub.m --C.sub.n --B.sub.p --C.sub.q --Hin which:B is the following group: ##STR3## C is the following group: ##STR4## and in which the indices m, n, p, and q are respective integers lying in the range 0 to 4, it being understood that the sum m+n+p+q is limited to integers in the range 0 to 4.The ester can be used for preparing cosmetic or pharmaceutical, in particular dermatological, compositions having activity against radicals, against inflammation, favoring differentiation of keratinocytes, improving skin moisturizing, improving skin grain fineness, and having anti-aging or depigmenting activity.

Abstract: The object of the invention is the use of a Bertholletia extract, particularly a Bertholletia excelsa extract, for the preparation of a cosmetic or pharmaceutical composition, particularly a dermatological composition. The Bertholletia extract promotes collagen synthesis or has activity against free radicals, for example to combat the effects of skin ageing, to prevent the formation of wrinkles or reduce their depth, or to promote firmer skin. It also has an activity for promoting the incorporation of vitamin C in the skin cells.

Abstract: The invention concerns novel uses of an Eriobotrya japonica extract, in particular in cosmetics or pharmaceutics. This extract permits stimulation of glycosaminoglycan synthesis, in particular of hyaluronic acid, thus imparting to the cosmetic compositions containing this extract the properties of improving the firmness and suppleness of the skin, combating the formation of wrinkles or lessening the depth thereof, smoothing the surface of the skin by means of a tightening effect, or moisturizing the skin. The invention further concerns the use of these extracts for stimulating the synthesis of glycosaminoglycans from a cell culture medium, in particular fibroblasts or keratinocytes.
