Collagen is the main structural element of the skin, it’s responsible for its characteristic properties, such as firmness and tonicity. Collagen’s role is to maintain the structure and resistance of the skin, creating a network which anchors the layers of the skin and forms a support base for components such as elastin, to maintain skin elasticity and hyaluronic acid to lock in moisture. Collagen fibres, constructed within skin cells (fibroblasts), are responsible for the maintenance and resistance of the skin. The presence of collagen peptides regulates the activity of fibroblasts in the skin and stimulates production of both collagen and hyaluronic acid, which is important for skin hydration. PURTIER Placenta contains marine collagen that has great beauty benefits to prevent the skin from aging, along with our stem cell Deer Placenta, it can anti-age and reverse aging.
