Hyaluron Acid Day Cream is used for intense hydration, skin smoothing, and replenishment, with added sun protection (SPF) to shield against UVA/UVB rays. It is enriched with a high concentration of two types of hyaluronic acids: – High molecular hyaluronic acid helps moisturize and smooth the skin's surface. – Small hyaluronic acid helps rejuvenate the skin by infusing moisture deep into the skin.
