Supplementing with specific collagen peptides can efficiently renew and revitalize the collagen structure of the skin, highlighting the advantages of consuming collagen orally for maintaining skin health.
A pioneering pilot study published in ‘Dermatology and Therapy’ showcased the remarkable effects of a specialized nutritional supplement on skin health, offering a new avenue for combating the natural aging process. Over 12 weeks, nine women participants (aged 43 to 61 years) consumed a supplement rich in unique collagen peptides, which displayed an impressive ability to restore and enhance the dermal collagen network, typically weakened by age.
The researchers utilized cutting-edge techniques to assess the impact of the supplement on the skin's collagen fibres. By generating suction blisters on participants' forearms before and after the supplementation period, Dorothee Dähnhardt et al. employed high-resolution scanning electron microscopy to scrutinize changes in the collagen network's structure (fibre length and diameter). Immunohistochemistry and fluorescence microscopy helped evaluate hyaluronic acid levels in the extracellular matrix.
The included women followed the protocol rigorously. A dramatic 34.56% increase in the size of the collagen fibre network (p < 0.0001) was found alongside notable improvements in fibre cross-linking and length. Furthermore, the epidermal concentration of hyaluronic acid rose by 18.08% (p < 0.0001). No adverse effects were noted.
