Eucerin Hyaluron Filler Refill Day Cream SPF30 is an innovative anti-aging treatment designed to combat the effects of skin aging. Its unique formula combines high and low molecular weight hyaluronic acid, which works synergistically to fill deep wrinkles and provide deep hydration. High molecular weight hyaluronic acid improves hydration of the outer layers of the skin, while low molecular weight hyaluronic acid penetrates the deeper layers of the epidermis, where the most pronounced wrinkles form. In addition to its anti-wrinkle properties, this cream includes an SPF 30 sun protection factor, which helps protect the skin from premature aging caused by solar radiation. With packaging containing 90% less plastic compared to other Eucerin products, this product also contributes to a more sustainable cycle in facial care. How to use Remove the cap and insert the refill into the bottle. Apply in the morning to thoroughly cleansed face, neck and décolleté, avoiding the delicate eye area.
