A new randomized, double-blind, placebo-controlled clinical study shows that taking Peptan® collagen peptides goes beyond just helping smooth wrinkles. The study provides powerful scientific evidence that the oral supplement reduces skin pore visibility and strengthens hair, and proves these benefits happen at lower doses
Studies with radioactively labelled collagen-derived peptides show that soon after absorption they enter into target tissues, such as bone, cartilage, muscle and skin. In skin they could be detected until 14 days after administration. Thanks to these remarkable properties, and their specific bioactivity, studies in humans have shown that Peptan® collagen peptides improve skin hydration and dermal collagen density, reducing fragmentation of the dermal collagen network, which is a key factor in aging. In its most recent study, Rousselot sought to evaluate skin and hair properties after 90 days of daily supplementation with 5 g of Peptan® B collagen peptide. This supplementation led to significant improvements in skin appearance scores, dermal density and hair strength.
In this study, 30 women received 5 g per day of Peptan® B and another 30 women a placebo supplement. The skin properties on their cheeks and around their nose, eyes and mouth was investigated before starting, and after 45 and 90 days of supplementation, as were the characteristics of the hair.
Rousselot studied the skin of the participating women by taking high resolution images and scoring the appearance of wrinkles and skin pores by a softwareassisted method. Significant decreases in the wrinkles around the eyes and mouth, reduced scaliness and roughness of the skin, and a lower visibility of skin pores were observed only in the group that was taking Peptan®.
To investigate the effect of Peptan® on hair properties, the break force of the hair of trial participants was measured using a special texture analyzer system. After supplementation with Peptan®, the womens’ hair break stress values showed a statistically significant increase, which was not present in the control group. Such results show that oral Peptan® collagen peptide supplementation strengthens the hair. That can be especially important for aging hair, which is thinner and weaker than in younger people.
This study delivers solid scientific proof that Peptan® produced from bovine collagen provides the same benefits to those previously found for non-bovine collagen peptides. It further proves that Peptan® collagen peptides are effective for skin beauty at a daily dose of 5 g. It also reveals the novel finding that hair tests on people taking Peptan® show higher break strength. These results show that collagen peptides are therefore a very powerful nutricosmetics supplement adding to the benefits for skin appearance that have already been proven for Peptan.
