A cosmetic treatment process is provided herein useful for reducing fine lines, wrinkles, or fine lines and wrinkles. The process comprises contacting a composition to an area of the skin or tissue of a subject, wherein the composition comprises a substance encapsulated within a lipid vesicle comprising a lipid having one or more polyethylene glycol (PEG) chains. The lipid vesicle has a charged surface, and an electric voltage is applied directly to the area of the skin that is contacted with the composition, whereby fine lines, wrinkles, or fine lines and wrinkles are reduced.
