Pure Vitamin C10 reveals the full radiance of sensitive skin. It corrects signs of aging and improves skin quality. Apply in the morning to the face and neck, avoiding the eye area. Use with sunscreen. The lightweight texture absorbs quickly and leaves a soft, non-greasy finish. It is the perfect base for makeup. Pure Vitamin C (L-ascorbic acid) is the most biologically active form of Vitamin C, known for its ability to enhance the radiance and texture of the skin. However, the human body cannot produce this molecule, which is why the skin relies on external application.
