Hydration, elasticity and comfort: three key words associated with Hyaluronic Acid, an essential ingredient for fresh, smooth-looking skin.
Naturally present in the body, this ingredient can—like a sponge—hold up to 1000 times its own weight in water, helping keep skin soft and radiant.
The effect that hyaluronic acid has depends on its molecular weight. With a low molecular weight (20-100 kDa), it permeates the deeper layers of the epidermis, has a repairing, anti-ageing and firming effect, and stimulates the production of collagen. With a high molecular weight (1800-3000 kDa), it has a film-forming, smoothing (replumping) and surface-hydrating effect.
