The first comprehensive scientific publication of research into the anti-ageing benefits of Peptan collagen peptides from Rousselot has just been released.
Appearing in the Journal of Cosmetic Dermatology, this latest paper elevates the science behind collagen peptides taken as a supplement for skin beauty to the next level by revealing strong clinical evidence to prove Peptan’s ability to restructure the collagen network in deep skin layers. The newly published data also presents a statistically significant effect of Peptan collagen peptides on skin hydration explained by the stimulation of hyaluronic acid production.
This new compilation of skin health research performed by leading dermatological institutes Laboratory Cosderma and EC Biolab in France and the Souken Laboratory in Japan, features evidence from two double-blind placebocontrolled clinical trials on Asian and Caucasian women with different skin types, backed by further ex vivo studies on skin tissue. The clinical research showed highly important skin antiageing benefits: Peptan significantly decreased the fragmentation of collagen in the deep layer of the dermis by –18% after 4 weeks and as much as –31% after 12 weeks of intake. Peptan also significantly increased the density of collagen in the dermis by +9% after 4 weeks of intake. Skin hydration increased by an impressive 28%, counteracting the appearance of the dry skin that typically occurs through ageing. The ex vivo studies demonstrated Peptan’s anti-ageing effects from a mechanistic point of view with key findings including the positive impact of Peptan on the skin cell’s (fibroblast’s) ability to produce collagen fibres and glycosaminoglycans (GAGs) such as the moisture-trapping hyaluronic acid.
