Course Summary
This course focuses on non-invasive testing of human skin in vivo. Modern methods for testing the effects of skin care products will be discussed. The major emphasis will be on instrumental measurements of skin function. The course goal is to teach cosmetic scientists how the latest noninvasive methods for studying product effects on human skin in vivo can be used for research guidance and cosmetic claim support.

Who Should Attend
This course is designed to benefit anyone who has interest in applying clinical and biophysical methods in cosmetic science. Those responsible for performing such tests may benefit from detailed analysis of the methods and formulators may increase their understanding of how the benefits of their products can be tested.
