Clinical Study of a Facial Cream for Rosacea

This study aimed to evaluate the efficacy, tolerability, and safety of Eucerin Skin Relief Multi-Repair Cream containing the active ingredient SenSiCel™ in improving facial rosacea. A single-center, randomized, negative-controlled clinical intervention design was adopted. A total of 76 Chinese women aged 20-50 years with Fitzpatrick skin types III-IV and mild-to-moderate rosacea (IGA score 2-3, CEA score 2-3, ≤3 inflammatory papules/pustules) were enrolled. Subjects were randomized in a 1:1 ratio into the test group (using the investigational cream) and the control group (using non-soothing daily facial cream), with an 8-week intervention period and four visits scheduled at baseline, Week 2, Week 4, and Week 8. The primary endpoint was the change from baseline in the Investigator's Global Assessment (IGA) score at Week 8. Secondary endpoints included changes in persistent erythema score, inflammatory lesion count, skin hydration, transepidermal water loss, hemoglobin index, red area proportion, and results of subject self-assessment questionnaires (Likert scale, DLQI). Tolerability and safety were also evaluated via dermatologist assessments and subject feedback. Data were analyzed using descriptive statistics, paired t-test/Wilcoxon signed-rank test, and independent t-test/Wilcoxon rank-sum test. This study provides clinical evidence for a safe and gentle adjuvant skincare regimen for patients with rosacea and offers a reference for efficacy validation of skincare products containing active ingredients.
