KEY BENEFITS A proven low-irritation formula, 96% of sensitive skins found C-Tetra to be gentle on their skin.* RESULTS Vitamin C minimises the appearance of fine lines and wrinkles over time, while helping to visibly balance and brighten the skin tone. HOW IT WORKS Your skin contains natural antioxidants that work to defend against free radicals from the environment. When these environmental free radicals outweigh your skin’s antioxidants, the skin can no longer protect itself. Free radicals latch onto the defenceless skin cells, causing irreparable damage, which ultimately leads to signs of premature skin ageing. KEY INGREDIENTS Tetrahexyldecyl Ascorbate (Vitamin C) & Vitamin E
