Eucerin Hyaluron-Filler Skin Refining Serum is a facial serum that helps refine the skin and smooth the first fine lines. The texture is incredibly light, suitable for all skin types, even acne-prone skin. Non-greasy and non-sticky, the formula is so lightweight that it works as an excellent makeup base, even for those with oily skin. With hydrating and exfoliating acids, the formula helps rebalance, replenish, and renew skin simultaneously. Hyaluronic acid is deeply hydrating and helps maintain the skins natural moisture. Additionally, glycolic acid, an incredible exfoliating acid, removes dead skin cells, refining skin texture while boosting radiance. Lactic acid also helps refine skin while helping to absorb and retain moisture. Equally important, sodium ascorbyl phosphate, a form of vitamin C, protects the skin with antioxidant and antimicrobial action. As a result, each application works to remove dead skin cells, refining skin texture and replenishing skin with moisture at the same time. The formula also plumps the skin, helping to smooth early signs of aging, such as fine lines.
