The Hyaluronic Serum Sealer enhances your daily routine to improve overall elasticity, softness and skin durability. It can aid in the penetration of other products, so its efficacy increases when layered with serums and moisturizers. It can also be blended with other products prior to application to adjust the feel or effects of such products (i.e. mix with a cream or lotion to make it lighter, or mix with another serum to increase its hydration factor).
