Iontophoresis is a well-known, noninvasive method that uses a small electric charge to deliver chemicals through the skin. However, according to Gregory Schultz, PhD, and Daniel Gibson, a professor and doctoral candidate, respectively, at the University of Florida, this method of delivery can have its drawbacks. Together with co-inventor, Sonal Sanjeev Tuli, MD, the team developed a method to iontophorese macromolecules into tissue such as the skin without causing damage; however, initial research focused on the eye.

As formulators create products for varying ethnic backgrounds and with diverse skin types, an understanding of differences in pigmentation and skin structure and function becomes more important. This column reviews recent studies on the structural, genetic and ultraviolet (UV)-responsive differences in skin pigmentation to allow the formulator to create successful products for varying ethnicities and to accurately measure pigmentation.
