Development of a Clinical Photographic Atlas for Skin Aging Based on the Characterization of Facial Dermal Collagen Using LC-OCT Technology

This is a single-center, single visit study conducted in healthy female subjects, aged 20 to 75 years inclusive meeting specific inclusion/exclusion criteria. The study is to develop a clinical photographic atlas to assess skin aging by studying the relationship between age, sun exposure and quantity of collagen measured non-invasively (LC-OCT). No product will be tested during the study.
