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.
