Objectives: The aim of this in vitro study is to investigate the effects on normal human dermal fibroblast synthesis of collagen I and elastin, matrix metalloproteinases MMP-1 and MMP-3, and elastin degradation of collagen bioactive peptides, alone and in combination with other bioactive compounds found in collagen-based nutraceuticals, previously reported to increase skin elasticity in vivo.
Our hypothesis is that the antioxidant activity associated with the additives within these nutraceuticals interacts with the effects of the collagen peptides to enhance the stability of matrix proteins.
Introduction: Nutraceuticals containing collagen peptides, vitamins, minerals and antioxidants are innovative functional food supplements that have been clinically shown to have positive effects on skin hydration and elasticity in vivo.
Materials / method: In this in vitro study, we investigated the interactions between collagen peptides (0.3-8 kDa) and other constituents present in liquid collagen-based nutraceuticals on normal primary dermal fibroblast function in a novel, physiologically relevant, cell culture model crowded with macromolecular dextran sulphate.
Results: Collagen peptides significantly increased fibroblast elastin synthesis, while significantly inhibiting release of MMP-1 and MMP-3 and elastin degradation. The positive effects of the collagen peptides on these responses and on fibroblast proliferation were enhanced in the presence of the antioxidant constituents of the products.
Conclusion: These data provide a scientific, cell-based, rationale for the positive effects of these collagen-derived peptides and other nutraceutical compounds on skin properties, suggesting that enhanced formation of stable dermal fibroblast-derived extracellular matrices may follow their oral consumption.
