This serum is packed with a superhero ingredient every skin type needs: vitamin C. Thanks to its antioxidant properties, vitamin C helps protect you from environmental aggressors, like pollution, blue light, and UV, to keep your skin healthy and youthful. Vitamin C suppresses excess melanin production to fade the look of existing dark spots and even prevent new ones from forming. Vitamin C stimulates collagen production to minimize fine lines, wrinkles, and sagging.
