Improved Skin Anti-aging Outcomes Associated With Collagen Fortified Consumption In 30 to 50-Year-old Women

The goal of this clinical trial is to study the efficacy of collagen supplement on the moisture content and elasticity. 70 participants of 30-50 years old women will be enrolled from two study sites and randomly assigned to use two products (study product plus collagen supplement and placebo product without collagen supplement) for 2 months. Researchers will compare the two groups to validate the assumption that there is significant improvement on skin anti-aging effect for participants using study product plus collagen supplement.
