About this study

Official title: The Effectiveness of a Whitening and Anti-Aging Bilayering Serum and Cream Containing Gamma-Aminobutyric Acid (GABA) 3%, Dimethylaminoethanol (DMAE) 2%, Cysteamine 2.5%, and Bakuchiol 1%

This study aims to evaluate the clinical efficacy and safety of a multi-functional bilayering skincare regimen-consisting of a serum and cream-for improving skin brightness and reducing wrinkles. The formulation combines four active ingredients: Gamma-Aminobutyric Acid (GABA) 3%, Dimethylaminoethanol (DMAE) 2%, Cysteamine 2.5%, and Bakuchiol 1%. In an 8-week, double-blind, randomized, placebo-controlled trial involving 44 female subjects with Fitzpatrick skin types III-V, investigators will assess changes in skin brightness (L-value), wrinkle scores, pore counts, and melanin/erythema indices using standardized imaging and measurement tools. The primary goal is to determine if this specific combination therapy significantly enhances skin whitening and anti-aging outcomes compared to a placebo.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Skin Luminance (L*) as measured by Chromameter.

    Skin color is assessed using the CIE Lab* system. The L* parameter specifically measures luminance/brightness on a scale of 0 (black) to 100 (white). An increase in L* value indicates an improvement in skin lightness

    Measured: Baseline (Day 0) and Week 8 (Day 56).

  2. Percentage change in skin wrinkles as assessed by Skin Analyzer.

    The Skin Analyzer evaluates the depth and area of facial wrinkles through digital imaging, providing a percentage value of the analyzed area. A lower percentage indicates a reduction in wrinkle appearance.

    Measured: (Day 0) and Week 8 (Day 56).
