Evaluation of a Food Supplement with Collagen Hydrolysate and Micronutrients on Skin Appearance and Beauty Effects: A Randomized, Double-Blind, PlaceboControlled Clinical Study with Healthy Subjects

Abstract

Objective: Skin health, skin appearance and skin beauty are influenced by collagen composition of the dermis. Natural aging affects the structural integrity of the collagen network, resulting in drier skin, wrinkle formation and reduced skin elasticity. Orally ingested hydrolyzed collagen reaches the skin tissue and exerts beneficial effects on human skin from within. However, not only collagen peptides, but also micronutrients can beneficially affect skin appearance. Thus, dietary supplements for cosmetic and beauty effects containing combinations of collagen peptides and selected micronutrients are in demand. Aim of this study was to investigate the effect of a food supplement with collagen hydrolysate and micronutrients on skin beauty. The test product was assessed for its capability to reduce wrinkles and to improve skin hydration and collagen structure.
