The Kristals Cosmetics AMBER Multi-Vitamin C Brightening Serum contains a cutting-edge form of vitamin C known as ascorbyl tetraisopalmitate which goes deep into facial skin cells to lighten, brighten and correct skin tone. We pair ascorbyl tetraisopalmitate with isopropyl palmitate—a great emollient—to improve skin softness, making it appear and feel smoother and less prone to dryness while reducing fine lines and pores. We synergize this formula with nourishing vitamin E and powerful red algae (astaxanthin), both of which are antioxidants and free radical fighters that combat premature aging. Finally, the Amber Multi-Vitamin C Brightening serum also incorporates vitamin A to promote skin renewal and to reverse the effects of sun damage on the skin.
