{"type":"trials","record":{"id":39417,"source_id":"clinicaltrials-gov","external_id":"NCT07409675","title":"Development of a Clinical Photographic Atlas for Skin Aging Based on the Characterization of Facial Dermal Collagen Using LC-OCT Technology","brief_summary":"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.","overall_status":"Completed","phases":[],"study_type":"OBSERVATIONAL","sponsor":"Vichy Laboratoires","enrollment":250,"countries":["France"],"start_date":"2024-11-06","completion_date":"2025-02-19","last_update_date":"2026-02-13","source_url":"https://clinicaltrials.gov/study/NCT07409675","editorial_summary":"A registered study indexed because it matched monitored longevity research terms.
