The unique, triple-action formula offers multiple anti-ageing benefits to reduce advanced signs of ageing: Eucerin's unique ingredient Arctiin stimulates collagen production and improves skin elasticity. The patented thiamidol visibly reduces age spots and makes the skin appear more even and younger. Eucerin's innovative blend of high and low molecular weight hyaluronic acid provides intensive moisturisation that regenerates and smoothes the skin. The result: even, firmer and rejuvenated looking skin that feels smooth and supple. Melanin is a natural pigment that gives the skin its colour. Sun exposure, hormonal influences and the ageing process can lead to increased melanin production and trigger hyperpigmentation. Hyperpigmentation manifests itself in the form of dark spots and age spots (also known as sun spots), which make the skin look uneven.
