This is a single-center, parallel-arm, 4-week interventional study designed to evaluate the lifting and firming efficacy of two facial care regimens in middle-aged Chinese women. Participants were randomly assigned to use either a retinol-based day cream or a lotion-and-toner bundle. The study included dermatologist assessment, standardized facial photography, and self-assessment questionnaires. A total of 132 healthy women aged 45-55 with facial skin sagging were enrolled. The primary objective was to compare improvement in lifting grades after 4 weeks of product use. The trial was conducted at China-Norm Quality Technical Service Co., Ltd., in Shanghai, China.
