The invention relates to the use of mixed silicates capable of forming, after application at a concentration of 3% in water at acid pH then drying, a film permeable to water vapor producing a retraction of the isolated stratum corneum greater than 1.5% at a temperature of 30 ° C and a relative humidity of 40%, as tensing agents to stretch the skin and smooth it in order to immediately reduce wrinkles and / or fine lines. It also relates to cosmetic compositions containing these mixed silicates at acid pH. |
