Summary

This is a randomized, double-blind, placebo-controlled clinical trial exploring the effects of a 12-week dietary supplement regimen on skin condition and perceived overall health status. The study will involve 120 healthy Chinese adults aged 18 and above with low daily fruit and vegetable intake. Participants will be randomly assigned to one of two groups: one group will take a combination of Nu Skin's Vitamin C \& Green Tea Capsules and Multivitamin \& Mineral Capsules, while the other group will take a matching placebo. The primary goal is to assess if the supplement combination improves skin health after 12 weeks, measured through specialized facial imaging (assessing spots, redness, evenness) and probe measurements (assessing elasticity, moisture, gloss). Secondary goals include evaluating changes in participants' self-perceived health status (via quality of life, fatigue, and digestive health questionnaires), psychological resilience, memory, and exploring a new method for measuring skin carotenoid levels. This study is not intended to verify the approved health functions of the products but to explore the potential combined effects of antioxidant and nutritional supplementation on skin and general well-being.
