a) en mode nettoyage sur peau sèche, le décollement du patch aprèsnapplication permettant, sous l'action mécanique résultant de l'adhérence dunpatch, de débarrasser la peau des impuretés qu'elle contient, ou b) en mode traitement à l'état mouillé, le (ou les) composé(s)nhydroabsorbants permettant d'une part, de conserver une adhérence de lanmatrice sur la peau, laquelle adhérence est réduite par rapport à adhérence denla matrice sur peau sèche, et d'autre part, en absorbant de l'eau, denresolubiliser tout ou partie des composés cosmétiquement actifs contenus dansnla matrice. Patch and cosmetic treatment method for the skin using this patch, the latter consisting of a polymer matrix, said matrix being self-adhesive on dry skin, and containing at least one cosmetically active compound, and at least one water-absorbing compound , said method consisting in selectively applying the patch: a) in cleaning mode on dry skin, detachment of the patch after application allowing, under the mechanical action resulting from the adhesion of the patch, to rid the skin of the impurities which it contains, or b) in wet treatment mode, the water-absorbing compound (s) making it possible, on the one hand, to maintain adhesion of the matrix to the skin, which adhesion is reduced compared to adhesion of the matrix to dry skin, and secondly, by absorbing water, to resolubilize all or part of the cosmetically active compounds contained in the matrix. |
