Erythematous Telangiectatic Rosacea
Conditions
Brief summary
In total, 72 eligible research participants were recruited in this 56-day study. The participants were divided into two groups-namely the Experimental Group and the Control Group-according to stratified randomization, with 36 participants in each group. Finally, 30 participants in each group were expected to complete the study. In this study, for patients with rosacea accompanied by sensitive skin, differences in repairing effects and other improvements were evaluated after they used LA ROCHE-POSAY CICAPLAST BAUME B5+ and a standard cream for 28 days, as well as differences between the two groups after both groups used LA ROCHE-POSAY CICAPLAST BAUME B5+ for an additional 28 days-via objective instrumental measurements and subjective assessments. Additionally, the safety of the investigational product was evaluated among these individuals.
Detailed description
During the first phase, both the Experimental Group and the Control Group cleanse their face in the morning and evening according to their daily habits, and should maintain their usual cleansing method, product brand, dosage, etc. The Experimental Group uses the investigational product on the whole face (twice a day), while the Control Group uses the placebo product on the whole face (twice a day). Both groups use standard sunscreen in the morning. During the second phase, both groups use the investigational product on the whole face (twice a day) after cleansing according to their daily habits in the morning and evening, and use standard sunscreen in the morning. During the entire test period, research participants are not allowed to use any other facial skin care products except the provided investigational product or placebo, and the standard sunscreen. The measurements will include clinical grading by dermatologists at Baseline (Day 0), Day 14 (after 14 days of application), Day 28 (after 28 days of application), Day 56 (after 56 days of application); Corneometer, Tewameter, pH meter, Chromameter, PeriCam PSI NR, VISIA; and self-grading at Baseline (Day 0), Day 14, Day 28, Day 56. Self-assessment will be conducted at Day0min (immediately after application), Day 14, Day 28, and Day 56. The 10% lactic acid stinging response test will be measured at Baseline (Day 0) and Day 28.

Design outcomes
Primary

| Corneometer | Baseline(Day 0), Day 14, Day 28, Day 56 | Skin hydration.The increase of Corneometer value indicates improvement of water content of skin. |
| Tewameter | Baseline(Day 0), Day 14, Day 28, Day 56 | Transepidermal water loss test. The lower value of TEWL indicates the better skin barrier function. |
| Chromameter | Baseline(Day 0), Day 14, Day 28, Day 56 | a\* value. the smaller the value,the less red the skin . |
