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. 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: The invention relates to the use of an extract of the alga Phaeodactylum, particularly the alga Phaeodactylum tricornutum, as a cosmetic agent promoting the proteasome activity of skin cells, particularly keratinocytes, fibroblasts or melanocytes (preferably human). The invention makes it possible to manufacture a cosmetic composition for protecting the skin from the adverse effects of UV exposure or for preventing and/or delaying skin ageing effects.

Abstract: The invention relates to the use of an extract of the alga Phaeodactylum, particularly the alga Phaeodactylum tricomutum, as a cosmetic agent promoting the proteasome activity of skin cells, particularly keratinocytes, fibroblasts or melanocytes (preferably human).
