Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This goal of this clinical trial is to study the efficacy of collagen supplement on skin moisture and elasticity in middle-aged women of 30-50 years old.

Participants will be assigned two products with and without collagen supplement and use for 2 months, twice a day.

Researchers will compare the two groups whether there are siginificant improvement of skin moisture and elasticity for participants via skin measurement and anaysis system.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a two arms, randomized, double-blind controlled trial. Study product plus collagen supplement and placebo product but without collagen will be randomly assigned to 70 eligible participants who will be enrolled at two study sites in Shanghai. Participants need to use the assigned product one bottle (25ml) each time, twice a day and visit the study site for three times (baseline day, day 30 and day 60) during the 2-month study. For each visit, the primary outcomes (skin hydration and skin elasticity) and secondary outcomes (skin barrier, lines/wrinkles, and facial glow,etc.) will be measured with professional equiment and imaging system and recorded to data management system. At the end of the study, the study data will exported and analyzed to validate the assumption that the collagen could improve skin moisture content and elasticity in middle-aged women of 30-50 years old.
