Two key antioxidants vitamins C and E make the C-Tetra your new Holy Grail serum. Perfect for everyday use with its light formula, C-Tetra sinks past the defensive lipid barrier and deep into skin, for extra protection against sun and pollution-induced damage.

This formula visibly stimulates the production of collagen and elastin while also brightening and balancing skin tone as it protects your skin from premature ageing. C-Tetra uses tetrahexyldecyl ascorbate, an uber-effective source of vitamin C that not only allows for deeper penetration, but results in less irritation important for sensitive skin types. Brightness is then boosted by red ginseng and maracuja oil, which is naturally rich in vitamin E. Vitamin E perfectly complements the vitamin C, delivering a nourishing dose of hydration to give a soft, glowy complexion. As luxurious as it is efficient, C-Tetra treats you to an uplifting scent of sweet orange, sans any artificial fragrances the perfect way to begin your morning.

After cleansing in the morning, massage 4 drops across the face, neck and decolletage. Leave to absorb before applying moisturiser.
