  • Vitamin E — an antioxidant that deeply nourishes and softens the delicate eye area.
  • Jojoba seed oil — the lightweight base of the formula.

No artificial fragrance. No synthetic colours. Paraben free. Alcohol free. Certified by the Vegan Society.

How to use

Patch test at least 24 hours before first use.

  • After cleansing in the morning, apply a small amount across the brow bone and under-eye area.

  • Follow with your vitamin C serum across the rest of the face, then sunscreen.

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

FAQ

How is it different from the C-Tetra face serum?
Same stabilised vitamin C, formulated for the delicate eye area rather than the whole face. The two are designed to be used together.
How do I use it with my C-Tetra serum?
After cleansing in the morning, apply this around the eye area first, then apply your C-Tetra across the rest of the complexion.
Can I use it alongside a vitamin A serum?
Yes. Medik8 recommend vitamin C in the morning and vitamin A at night.
Can I put it on my eyelids?
No. Apply across the brow bone and under-eye area only.
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 first.
