Clinical Efficacy and Safety of MB LuxuryⓇ Product Containing Epigallocathecin Gallate (EGCG) on Erythema, Melanin, and Skin Hydration

The purpose of this study is to evaluate the efficacy and safety of MB Luxury skincare containing the active ingredient Epigallocatechin Gallate (EGCG) from green tea (Camellia sinensis L.) on skin melanin index, erythema index, and skin moisture levels over 84 days of use. This is a quasi-experimental study with a nonequivalent control group pretest-posttest design. A total of 300 respondents were assigned to the intervention group (using MB Luxury twice daily for 84 days) and 50 respondents were assigned to the control group (receiving no product during the same period). Study details include: * Study Duration: 84 days (12 weeks) * Treatment Duration: 84 days * Visit Frequency: Measurements were taken at baseline (Day 0) and at weekly intervals (Day 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, and 84) for the intervention group. For the control group, measurements were taken at baseline and Day 84. * Health Measurements: Melanin and erythema indices were measured using Mexameter® MX 18, and skin moisture was measured using Corneometer® CM 825. The study aims to answer the following research questions: 1. Does MB Luxury significantly reduce melanin index after 84 days of use? 2. Does MB Luxury significantly reduce erythema index after 84 days of use? 3. Does MB Luxury significantly improve skin moisture after 84 days of use? 4. How do the changes in the intervention group compare to the control group? MB Luxury is not available through an expanded access program.
