Vitamin C (ascorbic acid) is a nutrient your body needs to form blood vessels, cartilage, muscle, and collagen in bones. In cosmetics, it's the vitamin of choice for dull complexions that want to regain their radiance and even out their complexion (anti-dark spot action) by limiting the overproduction of melanin. However, when pure, it is also unstable, degrading very quickly in the presence of light or heat. To guarantee its performance in our formulas, Clarins Laboratories have selected a stabilized vitamin C derivative.
The National Library of Medicine study shows that daily vitamin C formulation use for at least three months improved the appearance of fine and coarse wrinkles of the face and neck.
