Collagen is the main protein in connective tissue. It helps to maintain the firmness, tone and turgidity of the skin, making it a valuable ally against skin ageing. Collagen is therefore one of the main factors that help to maintain a healthy skin. With advancing age, the synthesis of new collagen decreases, and its degradation increases. The supply of type I Collagen in the dermis stimulates the cells used for its production, called fibroblasts, to reproduce generating neo-collagen. Because the contribution of collagen from the outside is effective it is important that this maintains perfectly the characteristics of the native one even after its extraction. The production technology must absolutely respect its biological structure, strictly maintaining its purity with the absence of chemical residues.
