The most advanced hydrating serum we’ve seen, Lamelle Hydrating HA PLUS Serum. Before HA , you’ll likely have dry, dull, sensitive skin that’s prone to fine lines and wrinkles. After Correctives HA , you’ll notice remarkable hydration in as little as one hour. It’s made with four different types of hyaluronic acid, each with a unique hydrating effect on your skin, as well as special HAFi fragments that stimulate your skin’s own hyaluronic acid production. For the first time in skincare, a hyaluronidase inhibitor protects aging skin against the aggressive breakdown of hyaluronic acid in your skin.
