Abstract
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.
