Definitions
- the disclosure generally relates to systems and methods for improving deliver ⁇ ' of topical actives and, more specifically, systems and methods for improving delivery of topical actives by using polymers to tension the skin.
- a system for improving the delivery of one or more topical actives includes at least one polymer effective to mechanically tension an area of skin to which the system is applied and the one or more topical actives,
- a method for improving the delivery of one or more topical actives includes applying to an area of skin a composition including at least one polymer effective to mechanically tension an area of skin and the one or more topical actives.
- the one or more topical actives are delivered to the area of skin at an improved rate or to improved depths as compared to a rate or depth of delivery achieved by application of the one or more topical actives applied to the area of skin alone.
- Various aspects provide a system for improving delivery of one or more topical actives to the skin of a subject
- the system includes at least one polymer effective to mechanically tension an area of skin to which the system is applied and optionally one or more topical actives.
- the polymer effective to mechanically tension the area of skin may be an acrylate copolymer.
