    Abstract: A method of protecting an active ingredient before using as a skin treatment includes packaging the active ingredient in a water soluble polysaccharide. The package includes a substrate, comprising a first and second side configured to bring together the water soluble polysaccharide with the active ingredient and a hydrogel, wherein the first side includes the water soluble polysaccharide with the active ingredient on the exterior, and the second half includes the hydrogel on the exterior. Once brought into contact for a sufficient time to allow the polysaccharide to dissolve, at least the hydrogel layer with the infused active ingredient can be peeled from the substrate to use as a facial mask for treating the skin with the active ingredient.
