Abstract
A cosmetic product is provided for delivery of skin actives through adhesive strips which concurrently remove keratotic plugs from skin pores. The product is a strip including a flexible substrate sheet onto which a composition containing an adhesive polymer is deposited. The composition is essentially a polymer of anionic, cationic, nonionic, amphoteric or zwitterionic variety which increases in tackiness upon being wetted, with wetting occurring just prior to application onto the skin thereby enhancing the composition's adhesivity. Skin agents delivered through the adhesive strip include vitamins, herbal extracts, alpha- and beta-hydroxycarboxylic acids, ceramides, anti-inflammatories, antimicrobials, vasoconstrictors, zinc salts and mixtures thereof. The strips are sealably enclosed within a pouch for purposes of moisture protection.
