Medik8 CE-Tetra Super Antioxidant Serum



Breakthrough Vitamin C serum

We love Vitamin C, but it’s hard to stabilize (which is why it tends to be on the pricey side). Medik8's ultra-stable CE-Tetra serum contains 7% Tetrahexyldecyl Ascorbate, the most potent and highly stable form of Vitamin C on the market, which has up to 4 times the potency of L-ascorbic acid and other forms of Vitamin C — without the irritation typically found with Vitamin C products. The superstar CE-Tetra formula also contains natural vitamin E, which makes the formula even more stable and potent, and it’s suitable even for acne-prone skin. CE-Tetra fights sun damage, improves skin’s texture, and brightens the complexion while providing excellent antioxidant protection. It’s the perfect anti-aging solution for those in their mid-20s through their 40s.
