Abstract
The invention relates to the use of an extract of prunella or at least one prunella saponin. This extract or this saponin is used for the preparation of a cosmetic or pharmaceutical and/or dermatological composition. Said composition makes it possible to regulate the renewal and differentiation of the keratinocytes and has an anti-aging activity, an anti-inflammatory activity, especially in inflammations caused by ultraviolet radiation, or an anti-allergic or anti-free-radical activity. It also enables the epidermis of normal skin to be kept in good condition, especially by maintaining the functional role of the skin, in particular as a protective barrier, and makes it possible to prevent or treat dry skin, especially ichthyotic skin, and to treat psoriasis.
