Powerful Vitamin C + E Antioxidant Serum 

  • Helps protect the skin from free radicals
  • Helps to minimise pigmentation marks
  • Assists in preventing premature skin ageing

Sulphate-free. Soap-free


A high strength and stable vitamin C serum to help combat sun-induced damage to the skin, help trigger collagen production, increase the skin’s elasticity and density, as well as improve the skin’s texture and brighten the complexion. Contains higher strength of lipid soluble Vitamin C for enhanced penetration and stability.

CE-Tetra contains vitamin E which synergistically boosts the overall antioxidant effect. A higher (more than double) level of Vitamin C is included in CE-Tetra formula compared with C-Tetra. And the level of vitamin E is higher too. This formula is for people at any age who are seeking a higher strength vitamin C serum, and ideal for people in their 40’s or above who want to get cracking with strong concentration from the get-go. Remember that at too high a concentration, vitamin C can begin to have a negative effect. CE-Tetra has been carefully researched and optimised over 5 years with tens of thousands of users to get the best balance of potency, stability and minimal if any irritation. The high stability means that the vitamin C does not degrade over time, making CE-Tetra a highly potent serum 100% safe to use.
