Clinical Trial: Clinical Observational Study on Changes in Skin Physiological Parameters Following Ablative and Non-Ablative Fractional Laser Treatment at Different Doses

U.S., May 2 -- ClinicalTrials.gov registry received information related to the study (NCT07561242) titled 'Clinical Observational Study on Changes in Skin Physiological Parameters Following Ablative and Non-Ablative Fractional Laser Treatment at Different Doses' on April 13.

Brief Summary: This clinical observational study investigates the dose-response relationship between laser energy intensity and skin damage/repair by applying different parameter sets of fractional ablative (CO2) and non-ablative (M22) lasers to the inner forearms of approximately 20 healthy Chinese female volunteers (aged 18-60, Fitzpatrick skin types III-V) in a single-center, self-controlled design. Each participant receives both laser types on contralateral arms, w...
