92,273 Adobe Stock Hyaluron Serum. The power of plants has long been championed at Susanne Kaufmann. For our Hyaluron Serum, we use an intelligent combination of large and small hyaluronic acid molecules, as well as brown algae, which helps to bind moisture in the skin, leaving the complexion looking plumped and healthy. The lightweight gel texture absorbs quickly into the skin and is perfect for everyday use. For a hydrating boost for sun exposed skin or to care for dry skin in winter, apply the Hyaluron Serum under our Moisturising Mask and enjoy plumped, comforted skin. Due to the use of active, natural ingredients, this product may appear cloudy. To make this product even more sustainable and performant, we recently made a minor improvement to the formula by switching to some new, intelligent ingredient complexes from the Alpine region. This product still delivers the same benefits that you know and love, so you can achieve the very best for your skin while respecting our planet.
