These unique delivery technologies have the ability to entrap hydrophilic or lipophilic actives and deliver them to the dermis through extended release. The sustained delivery of actives leads to reduction in irritation potential for challenging actives, while providing prospective multifunctional benefits, i.e., adsorbing skin oil while the actives are being released.
Tretinoin ( retinoids), benzoyl peroxide, hydroquinone are commercially available entrapments.
These technologies are currently being marketed and sold in cosmeceutical, Rx and OTC formulations. Other actives may require some development.
