Abstract
This invention discloses compositions and method for treating various types of skin disorders, based on topical cutaneous delivery of copper chemically bound with botanical pigments. Sodium-copper-chlorophyllin is used as an example, showing benefits in the treatment of rosacea, acne, oily skin, enlarged pores, and in relieving skin inflammation. Benefits are also disclosed in treatment of environmentally caused premature skin aging, via reductions in fine facial lines and wrinkles, increased tensile strength of the skin, and increased protection against sunlight via increased production of melanin. Therapeutic outcomes are improved when the copper-pigment complex is enclosed within submicron liposomes.
