This clinical study is a single-center, randomized, split-face, on-site controlled trial conducted at Shanghai China-Norm Quality Technical Service Co., Ltd. The primary objective is to evaluate the efficacy of Eucerin Ultrasensitive Repair Intensive Source Serum in providing instant and long-lasting (24-hour) soothing and repairing effects under induced redness conditions. The design involves recruiting 30 healthy Chinese female subjects aged 18-60 years, who meet stringent inclusion/exclusion criteria, including absence of skin conditions and no recent participation in similar studies. Redness is induced using 50% Glycolic Acid on the entire face and tape stripping on both forearms.
