Abstract
The invention provides a method for applying a plurality of compositions, preferably two, containing a dermatological or other therapeutical agent to the skin from a single dispensing and applicator system. The system has a plurality of compartmentalized applicator pads which may be exposed and sequentially or simultaneously applied to the skin area to be treated. The system is useful for administering separate phases of an occlusive or semi-occlusive film-forming solution for treating pathologies of the skin. When the phases are applied to and dried upon the skin, a polymeric film forms to retain the therapeutical agent in contact with the surface of the skin.
