Medik8 C-Tetra Eye Serum 7ml

The C-Tetra formula adapted for the eye area. C-Tetra Eye uses 3% stabilised vitamin C to brighten under-eye darkness and soften the look of fine lines, in a lightweight serum that absorbs fast and will not drag or sting.

Tetrahexyldecyl ascorbate is the same low-irritation vitamin C used across the C-Tetra range, chosen here because the skin around the eyes is thinner and more reactive than the rest of the face. Vitamin E adds antioxidant protection against the free radical damage that shows up first in this area.

Used each morning, it leaves the eye contour looking brighter, smoother and more awake. The serum texture means it layers under concealer without creasing, which a richer eye cream often will not.

It is a daytime product by design - vitamin C is an antioxidant, so it earns its place in the morning routine alongside sunscreen. Pair it with Advanced Night Eye or Crystal Retinal Ceramide Eye in the evening.

Apply a small amount around the orbital bone after cleansing, before your moisturiser and sunscreen.

The eye area needs its own products, not smaller amounts of the face ones. Run C-Tetra Eye Serum in the morning and Advanced Night Eye, Crystal Retinal Ceramide Eye or Intelligent Retinol Eye TR at night for a complete eye routine.
