The Mario Badescu Brightening Serum is a lightweight formula that revitalizes the appearance of tired eyes. Enhanced with caffeine, the serum visibly reduces puffiness and dark circles, while a blend of squalane, niacinamide, and hyaluronic acid hydrates. The multi-use treatment also helps to smooth fine lines in the eye contour area. Use it alone or in combination with your favorite Mario Badescu eye cream for extra brightness. Vegan.
