Harmful environmental influences can put quite a strain on our skin: UV radiation, big-city smog etc. facilitate premature skin-aging. We have developed a product which protects the skin against negative environmental influences like a natural protective shield and at the same time helps to mitigate any damage that already exists. What’s more, it also has a confirmed anti-aging effect, reduces wrinkles and protects against hyperpigmentation. We proudly present: the newBIRKENSTOCK NATURAL SKIN CARE Vitamin C Serum!
