Peptan® collagen peptides go beyond just helping smooth wrinkles. Adding further evidence to Peptan’s strong scientific portfolio, a new clinical study revealed that supplementation with Peptan significantly contributes to improving the overall appearance of skin and hair in an ethnically diverse population.

Sitting underneath the skin’s outer epidermis layer, our dermis gives skin strength and firmness. As people age, the dermis changes structure because its collagen network breaks up and thins. At the same time skin fibroblast cells slow down production of the matrix that surrounds them, and degraded matrix components are not replaced fast enough. This leads to loss of skin elasticity, hydration and strength, causing visible sagging and wrinkle formation.

Thanks to the remarkable properties of collagen peptides, 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 network1, helping to reduce the signs of aging.

This new clinical study provides powerful evidence that supplementation with Peptan (Type 1) collagen peptides reduces skin pore visibility and strengthens hair2.

The randomized, double-blind, placebo-controlled study was conducted with 60 healthy Brazilian women, aged 45 to 60 years. During a set period of 90 days, participants received a 5g daily dose of Peptan collagen peptides from bovine origin. Results showed significant improvements in the overall appearance of the skin;

  • A decrease in periorbital wrinkles (around the eyes) by 13% and nasolabial wrinkles (from bottom of the nose to the corners of the mouth) by 10% and
  • A reduction of the visibility of pores in the region of the cheekbones in 57% of the Peptan-supplemented participants.

An increase of the density of the dermis, which contains the strength-providing collagen layer of the skin, following Peptan supplementation, was at the basis of these observations.

This study also revealed a 13% increase in the mechanical strength of hair. (Mechanical strength is linked to improved properties of the hair cortex, which can be especially beneficial for aging hair).

Conducted in a Brazilian population of mixed skin and hair types, this study brings proof that Peptan is effective across populations of different ethnical backgrounds, adding to previous evidence obtained from trials in Caucasian and Asian populations.
