Hyaluronic acid is a highly unique molecule, extracting moisture from the environment, and holding 1,000 times its weight of it in the skin! Naturally produced by our bodies, the hyaluronic acid in our skin depletes as we age. This supple serum allows for immediate absorption into the skin, without the greasy finish. With this formulation, skin receives the benefit of hyaluronic acid much deeper than it would in other products, as it is bottled in its purest form. Use 1-2 times per day after cleansing for optimal results.
