They guarantee product performance and satisfy consumer expectations for more efficient cosmetic products. A trend towards application of highly active and often unstable substances for skin care purposes has been noticeable for some years. Thus, the choice of appropriate delivery systems has become crucial for cosmetic product development. This short paper reviews current encapsulation technologies, especially focusing on liposomes, micro-or nanoparticles, sponge-like microparticles and cyclodextrins. These delivery systems cover a broad range of chemically different actives and are effective in overcoming a variety of formulation hurdles. Currently, the main focus is on lipophilic actives, especially retinol. In this area, the aspects of sustained delivery and the reduction of unwanted side effects have been well addressed. For hydrophilic actives, however, efficient and applicable encapsulation methods are yet to be established. Another field for future innovations is improved bioavailability of the active at the target site and the selective triggering of drug release.
