Tapping pharmacological potential and assuring ingredients work most efficaciously on the skin are the prime aims of delivery systems for antiaging skin care. Informed consumers want to know that topical treatments are a viable alternative to invasive procedures, and technologically advanced delivery of highly functional ingredients is the major way to provide that assurance.
While the passage of the years can’t be stopped, technological advances in skin care have forestalled their imprint. Consumers are trying a variety of topical approaches, which in turn utilize a variety of delivery systems, and suppliers of functional ingredients are seeking the synergy of appropriate delivery systems to answer the demand.
Because a highly functional ingredient may be expensive, the proper delivery system will allow the ingredients to be metered out slowly without waste, and enable greater efficacy at a reduced overall cost. It also is important that system and formulation work together. Their compatibility aids in their efficacy.
Meyer Rosen, editor of Delivery System Handbook for Personal Care and Cosmetic Products(© 2005, William Andrew Publishing), cites the importance of functional actives, delivery system technology, applications and opportunities for technology licensing and differentiation. Numerous, innovative and in-demand, the systems are utilized in many products reaching consumers today.
“Delivery system technologies significantly enhance the power and flexibility of formulators by decreasing the amount of costly functional actives, protecting them from oxidation and reducing potential irritation due to undesirably rapid release,” says Rosen. “The delivery system, with its contained active, typically is put into many types of personal care and cosmetic formulations, and one must be mindful that the delivery system/active/formulation is a ‘new’ entity that must remain compatible and functional.”
