Collagen Supplement Improves Skin Attributes in Healthy Adults

Abstract

Abstract Objectives Consumption of supplements have been found to improve skin health, but there is only a limited number of studies to support these claims. The main objective of this single center, randomized placebo-controlled study was to determine the effects of a nutritional supplement containing collagen peptides, wheat extract oil containing ceramides, and lutein on skin appearance in healthy adults. Methods Sixty healthy, nonsmoking men and women between the ages of 40 and 75 years with Fitzpatrick skin types I and II were recruited to participate in the study. The variables measured were changes in skin attributes including skin color, skin carotenoids levels, skin hydration, and visible results as assessed by a dermatologist and self-assessment between groups given supplement: collagen peptides, ceramides, and lutein (CCL) or placebo. The study also investigated if using a facial cleansing device along with CCL influenced facial skin appearance. Results Skin carotenoid levels significantly increased from baseline with CCL at 30 and 120d with a mean increase of 10,750 Raman Intensity Units (RIUs) following 120d supplementation. Significant improvements in facial skin radiance, texture, and overall appearance were found for CCL, cleansing device or combination of both. An increase was found in skin facial color (b*) at 30 and 120d with CCL supplementation while placebo treatment was unchanged between baseline and 30d, but then increased between 30 and 120d. No changes in lines and skin firmness were noted. Conclusions Supplementation for 120d with CCL with and without a cleansing device supported skin health and improved several skin attributes thus confirming evidence of benefit on skin health and identifying potential for added benefit of device along with supplementation.
