| description | Skin care compositions containing microcapsules with a mean diameter of from 0.1 to 5 mm are disclosed. The microcapsules are prepared by a process comprising: (a) providing an o/w emulsion prepared by combining an aqueous preparation of a component selected from the group consisting of retinol and retinolic acid with an oil component in the presence of an emulsifier; (b) combining the emulsion and an aqueous solution of an anionic polymer to form a matrix; (c) contacting the matrix with an aqueous chitosan solution such that membrane-encapsulated products are formed in an aqueous phase; and (d) separating the products from the aqueous phase. |
