Biologique Recherche Serum Elastine is a smoothing, reconditioning serum that improves elasticity and softens fine lines and wrinkles. Its biomimetic elastin peptide helps reinforce the skin's structural network, restoring flexibility and bounce while preventing early wrinkle formation. Marine Exopolysaccharide stimulates collagen and elastin synthesis to improve the skin's firmness, smoothness and plumpness, while also providing a tightening benefit on the collagen fibre network for an immediate and durable lifting effect. Low Molecular Weight Hyaluronic Acid penetrates the epidermis to deeply hydrate and plump the skin from within, reducing the appearance of fine lines. Elastin Fragment — a hexapeptide — stimulates fibroblasts to produce more elastin and collagen, making the skin plumper, smoother, tighter and more hydrated. The Complex of Matrikines reinforces this action by stimulating the synthesis of these peptides and improving the environment in which they reside, resulting in a measurably firmer, more elastic and youthfully toned complexion with consistent use.
