C-Tetra works to protect the skin from free radical damage, featuring vitamin C to boost the natural antioxidant defence levels in the skin. Vitamin C is a key pillar of our CSA Philosophy, due to being one of the most powerful vitamins for preventing the signs of premature skin ageing. Vitamin C also helps to stimulate collagen production and can disrupt the overproduction of melanin to brighten the appearance of dark spots and uneven skin tone.
