Problems solved by technology

This adds cost and complexity to the manufacturing process if multiple printing stations are required to deliver sufficient doses of the active substance
If low viscosity fluids with excess water are used, multiple drying stations are required, again adding cost and complexity to the process

Abstract

A method of producing a multi-layer beauty care product for applying a skin active agent to the skin. The method involves applying a water-soluble fluid to a transfer substrate. The water-soluble fluid contains a skin active agent and is applied to the transfer substrate through an image carrier having a mesh size of 40 to 500. The water-soluble fluid is dried to form a water-soluble film, which is then transferred to a backing layer coated with a pressure sensitive adhesive. The resulting multi-layer beauty care product provides a suitable a means of delivering the skin care active agent to atarget portion of skin.

Description

technical field [0001] The present invention relates to a method for the preparation of a multilayered cosmetic care product comprising a barrier patch and a dissolvable film comprising a skin active agent for improving the appearance of the skin. Background technique [0002] The benefits of cosmetically treating the skin using patches or mask devices containing skin active agents have been recognized in the art. A variety of cosmetic patches are marketed and available for the delivery of skin actives. Patches have been described in the literature and marketed in the medical field as a useful means of transdermal delivery. [0003] Certain beauty care patch systems include an active substance reservoir in which the active substance is present in solid, liquid or dissolved form, and a pressure sensitive adhesive layer whereby the system can be brought into intimate contact with the skin. When the active substance does not diffuse through the adhesive layer, when a chemical...
