Rousselot (Son, Netherlands) released the results of an unpublished study demonstrating that its bovine-sourced Peptan collagen peptides ingredient supports the overall appearance of skin and hair in ethnically diverse populations. In the randomized, double-blind, placebo-controlled study, 60 Brazilian women of mixed skin and hair types, between 45 and 60 years of age were randomly assigned to either receive 5 mg of Peptan daily, or placebo for 90 days.

Results showed that subjects taking Peptan saw a 13% decrease in periorbital wrinkles, a 10% decrease in nasolabial wrinkles, and a reduction in the visibility of pores in the region of the cheekbones in 57% Peptan-supplemented participants. These results were attributed to an increase in the density of the dermis, which contains a strength-providing collagen layer of the skin.

Researchers also used a texturometer to evaluate the characteristics of subjects’ hair before and after supplementation. Results showed that supplementation increased the mechanical strength of hair by 13% compared to placebo, which is linked to improved properties of the hair cortex. This is particularly beneficial for aging hair.
