Skin analysis in trials have shown an increase of amino acid peptides:
A 2008 study in Tokyo of 33 women ages 40-60 who took 10 g of Hydrolyzed Collagen daily for 2 months showed 91% saw an increase in skin hydration and resilience.
A Dermiscan study in Lyon France in 2008 showed similar findings in an age group of 35-55: an increase in skin smoothness and hydration, using the Corneometer and Skin Image Analyzer technologies. [15, 16] After 12 weeks of 10g Hydrolyzed Collagen daily, 41% less furrowing, less wrinkles, more resilient, more hydrated.
Skin resilience was measured by the C&Z Cutometer, Hydrolyzed Collagen also increases the diameter of collagen fibrils in the dermis by the same mechanism: fibroblast stimulation. This in turn increases cohesion of the dermal collagen fibers themselves, which is a true anti-aging step. In the skin, this action means increased thickness, suppleness and resilience, as well as hydration.
Hydration, or water content of skin tissue, is proven directly related to overall smoothness and decreased furrowing and wrinkling. ([9] Sumida)
