Hyaluronic acid occurs naturally in the body and is a vital component in maintaining skin’s moisture content. This powerful molecule attracts and retains over 1,000 times its weight in water and is one of the foundations of the dermis, the layer that gives your skin fullness and plumpness. Hyaluronic acid serums penetrate the skin to hydrate, plump and smooth without clogging pores. These lightweight, moisturising serums are ideal for dry, oily, normal and aging skin. The SkinCeuticals hyaluronic acid serums contain HA combined with active ingredients to suit specific skin types and conditions.
