How to Use

Apply 3–4 drops to clean, dry skin every morning. Smooth over the face and neck, then follow with moisturiser and SPF.

Key Benefits

  • Visibly brightens and evens skin tone
  • Helps prevent the early signs of ageing
  • Ideal first vitamin C for sensitive skin
The Science Behind the Formula

Vitamin C is the skin's most important antioxidant, but pure ascorbic acid is unstable and can irritate. C-Tetra uses tetrahexyldecyl ascorbate, an oil-soluble vitamin C derivative that is stable and absorbs readily through the skin's lipid barrier, boosted with vitamin E to extend the antioxidant protection throughout the day.

Key ingredients

Tetrahexyldecyl ascorbate (vitamin C), vitamin E, antioxidant-rich botanical oils.
