This weightless, gel-like moisturiser contains a high-performance 5% vitamin C complex for a radiant, lit-from-within glow, plus ferulic acid to boost the brightening power of vitamin C. Essential hydrators work to restore hydration, while skincare powerhouse ingredient niacinamide evens skin tone and helps to diminish pore size. Why use a complex? Vitamin C’s pure form, ascorbic acid, is known to be unstable and highly susceptible to oxidation (resulting in it turning brown) via heat, light, air and water, which impacts its effectiveness. Using more stable derivatives of vitamin C in our formula ensures that rate of oxidation is slowed right down, meaning less discolouration and a longer shelf life, so your skin can get all the amazing benefits of vitamin C for longer. How it works – 5% vitamin C complex: A supercharged, innovative complex of 3 stabilised forms of vitamin C to ensure a more stable and effective brightening formula. – Niacinamide: Helps even skin tone. – Ferulic acid: A versatile antioxidant that boosts effectiveness of vitamin C.
