The skin around the eyes is the most sensitive and vulnerable on the face. It is a highly vascularized area where blood pigments (haemosiderin) accumulate, resulting in the purple color associated with black circles.k-vit Serum, with its composition of Vitamin K oxide contained in liposomes, minimizes the buildup of these blood pigments, improving the look of dark circles. Its formulation also includes plant-based active components such as camphanediol, pinanediol, hyaluronic acid, and organic silica, which serve to promote microcirculation and alleviate age-related symptoms in the eye contour area, such as bags and wrinkles.
