Abstract
In recent years, there has been increasing interest in active energy or minimally invasive technologies for cosmetic use and also to expand the scope of transdermal delivery to hydrophilic molecules and macromolecules. These molecules do not normally pass through the skin unless enabling technologies are used. Recent innovations in these technologies, especially for iontophoresis and microporation, will be presented. Microporation involves the creation of micron-sized micropores or microchannels in the skin which can then allow the transport of water soluble molecules. Skin microporation can be achieved by microneedles or by using thermal, laser, or radio-frequency ablation. Iontophoresis involves the application of small amounts of physiologically acceptable currents to drive ionic molecules into the skin. Technology behind products on the market such as Biobliss, Dermaroller, WrinkleMD and Zecuity will be discussed. The author has done significant research with both techniques in his laboratory with over 50 different drug molecules and cosmeceuticals.
