Abstract
A method and article for delivery of skin care agents. Freeze-dried liposomes are used to encapsulate agents for delivery to specific cells in the skin. The applicable agents include perfumes, moisturizers, vitamins and therapeutic compounds as well as others. The agents are encapsulated in liposomes specifically selected to carry the agents to the target cells thereby increasing effectiveness and efficiency and minimizing systemic absorption. The liposomes are at least partially freeze-dried to improve shelf-life and improve delivery to the skin. After freeze-drying, the liposomes are deposited on or in a fabric-like pad. The liposomes are rehydrated either immediately prior to application to the skin or on the skin using natural moisture or a hydrating solution. An applicator is also provided to secure and hold the impregnated pad during use. The applicator may provide steam or vapor to rehydrate the liposomes during application.
