  • 3% stabilised vitamin C (tetrahexyldecyl ascorbate) — a low-irritation form of vitamin C that gives antioxidant protection against free radical damage while brightening and supporting collagen production.
  • Vitamin E — an antioxidant that adds further protection against free radicals and helps boost the power of the vitamin C.
  • Hyaluronic acid — draws moisture from the lower layers of the skin into the upper layers, leaving the complexion visibly nourished and supple.

Medik8 say the vitamin C stays potent and effective for 6 months after opening.

FAQ

How is this different from the C-Tetra serum?
Same vitamin C technology, different format. The serums are oil-based; this brings it into a nourishing cream.
How is it different from Daily Radiance Vitamin C?
Daily Radiance does the same job but also carries SPF 30, so it replaces your sunscreen step as well.
Can I use it alongside a vitamin A serum?
Yes. Medik8 recommend vitamin C plus sunscreen by day and vitamin A by night.
Can I use it while pregnant or breastfeeding?
Medik8 say it contains no ingredients they would recommend avoiding during pregnancy, but advise discussing it with your doctor or midwife first.
Do I still need sunscreen?
Yes. Apply sunscreen after it, every morning.
