The results showed that Peptan decreased wrinkled in multiple parts of the face, and increased mechanical strength of hair.

Rousselot (Son, Netherlands) released the results of an unpublished study demonstrating that its bovine-sourced Peptan collagen peptides ingredient supports the overall appearance of skin and hair in ethnically diverse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.
