ABSTRACT
This chapter discusses the variety of delivery systems for novel cosmeceuticals. A variety of delivery systems have been developed to carry novel compounds to the skin. If a large quantity of water is found in the emulsion, it is considered a lotion, whereas a thicker emulsion with less water is considered a cream. Examples of substances that can be delivered in cosmeceutical emulsions include flavonoids, polyphenols, and carotenoids. A variant on nanoparticles is nanoemulsions, similar in construction to the emulsions previously discussed at the beginning of this chapter as the oldest delivery system. Nanoemulsions have successfully delivered higher concentrations of ubiquinone into the skin with the goal of enhancing the skin's natural antioxidant capabilities. If extremely sustained delivery to a targeted area is desired, transdermal patches may offer additional efficacy, discussed next. Liposomes, nanodelivery, microsponges, transdermal patches, paper delivery systems, and skin poration are a few of the currently available techniques to deliver novel cosmeceuticals.
