Image Processing and Analysis to Evaluate the Effects of Porous Polyamide Microspheres in Cosmetics

Described here is an image processing system that compensates for changes in illumination and volunteer position, and two algorithms to quantify skin texture and wrinkles. These methods evaluate skin parameters from a single image without contacting skin. Their abilities are demonstrated here in evaluations of the benefits of porous polyamide ultra-fine powders on skin texture and gloss.
