The images will be obtained with the 3D Clarity Pro® Facial Modeling and Analysis System (Brigh-Tex BioPhotonics, San Jose, CA) that has standardized positioning and lighting. This system can assess average wrinkle depth. The PI has already validated this measurement tool against standard clinical grading of facial wrinkles[13].
