Efficacy of a Nutritional Supplement on Skin Health in Generally Healthy Adults
Study Details
Study Description
Brief Summary
Consumption of dietary supplements has been found to modulate skin health. Individual ingredients such as collagen peptides, lutein and ceramides have been shown to improve skin health. Collagen peptides have been shown to clinically improve skin texture, decrease area of skin ultraviolet damage, increase skin hydration, and improve visible skin results such as hydration, elasticity, wrinkles and roughness. Lutein has been demonstrated to increase skin radiance, protect skin from ultraviolet light, and increase skin hydration. Ceramides derived from wheat have been shown to improve skin texture, increase skin hydration and improve visible skin attributes such as hydration, elasticity, and wrinkles. This study will have subjects consuming a nutritional supplement or placebo daily for 90 days to see if there is an effect on skin health. This study will also have the subjects using a facial cleansing device, which has been shown to improve skin health, on half of their face to determine if there is a synergistic effect between dietary supplement and cleansing device. It is believed, this mixture of collagen peptides, lutein and ceramides has not been studied and the study sponsor hypothesize that this blend of ingredients will have a positive impact on skin health.
