Abstract
A composition for use as a topical delivery system for an active material is provided, the composition comprising a plurality of skin cell removal particles and a plurality of active material molecules, at least some of the skin cell removal particles each carrying at least one active material molecule, wherein carrying of an active material molecule by a skin cell removal particle maintains activity of the active material molecule. A topical delivery system for an active material, and a method of topical delivery of an active material are also provided.
Claims17
A composition comprising a plurality of skin cell removal particles and a plurality of active material molecules,
- wherein the skin removal particles comprise at least one elemental silicon particle,
- wherein the elemental silicon particle has a jagged outer surface,
- wherein at least some of the skin cell removal particles each carry at least one active material molecule, and
- wherein carrying of at least one active material molecule by a skin cell removal particle stabilizes an activity of the at least one active material molecule.
A method for topical delivery of an active material comprising
- applying a composition to a portion of skin, wherein the composition comprises a plurality of skin cell removal particles and a plurality of active material molecules,
- wherein at least some of the skin cell removal particles each carry at least one active material molecule,
- wherein carrying of at least one active material molecule by a skin cell removal particle maintains activity of the at least one active material molecule;
- working the composition against the portion of skin to remove stratum corneum cells;
- dissociating the active material molecules from the skin cell removal particles;
- and
- delivering the active material molecules to sub-corneum skin layers.
