Medik8 C-Tetra Eye is a lightweight, fast-absorbing antioxidant serum designed specifically for the delicate eye area. Using the same brightening and anti-ageing power of the bestselling C-Tetra facial serum, it helps smooth fine lines, revitalise tired eyes and restore a brighter, more youthful appearance.

Formulated with 100% stable vitamin C (tetrahexyldecyl ascorbate) and vitamin E, this gentle yet effective treatment protects the skin against free-radical damage while helping to support collagen production. The synergistic antioxidant blend defends against environmental stress and brightens dullness without causing irritation.

The serum’s silky, quick-absorbing texture delivers lasting hydration and radiance, making it ideal for addressing early signs of ageing such as dryness, fine lines and a lack of firmness.

Benefits

  • Brightens and revitalises the delicate eye area
  • Smoothes the look of fine lines and early wrinkles
  • Lightweight, hydrating and gentle for sensitive eyes
  • Fast-absorbing with a soft citrus aroma
  • Protects against free-radical and environmental damage

Key Ingredients

  • Tetrahexyldecyl Ascorbate (Vitamin C) – Stabilised, gentle vitamin C that brightens, supports collagen and protects against free radicals
  • Vitamin E – Enhances antioxidant protection and supports skin healing
  • Jojoba Seed Oil – Lightweight moisturiser that softens and conditions
  • Hydrating Emollients – Help cushion the delicate orbital area for a smoother finish

After cleansing in the morning, use a spatula-style applicator (not included) to sweep a small amount of C-Tetra Eye across the under-eye and brow bone, avoiding eyelids. Gently blend.

7ml

Key Ingredients: Tetrahexyldecyl Ascorbate: A lipid-soluble form of vitamin C that provides exceptional antioxidant protection from harmful free radicals, while stimulating collagen production for a youthful complexion.

All Ingredients: Simmondsia Chinensis (Jojoba) Seed Oil, Cyclopentasiloxane, Cyclohexasiloxane, Tetrahexyldecyl Ascorbate, Tocopheryl Acetate, Citrus Grandis (Grapefruit) Peel Oil, Limonene.

Ingredient
Vitamin C
What It Is

Vitamin C is an essential nutrient required for the growth and repair of tissues in all parts of the body, including the skin, but we cannot produce it on our own. The powerful antioxidant is found naturally in fruits and vegetables and commonly produced synthetically in skincare products, such as moisturisers, toners, and, most often, serums.

What It Does

How to use in your skincare routine?

Whether your skin is dry, oily, or a combination, vitamin C is beneficial for skin health, helping it look and feel healthier and younger longer.

Before you apply the vitamin C, test a patch of skin with a lower-concentration formula to see how your skin reacts. Some minor tingling is normal, but if you experience anything more intense, stop using the product and talk to your dermatologist.

For best results, apply this vitamin topically 1-2 times a day, morning and night. Be sure to apply a moisturiser with a broad-spectrum SPF after vitamin C application for daytime.

Benefits
  • Vitamin C makes sun damage and surface pigment spots less visible and brightens a dull, blotchy skin.
  • It is a powerful antioxidant that protects the skin from irritation, inflammation and environmental pollution.
  • It reduces red blotches left after spots by improving the skin’s natural healing process.
  • It increases the effectiveness of sunscreen and gives the skin better protection from UV rays 
Vitamin E
What It Is

Vitamin E is a fat-soluble, essential nutrient with anti-inflammatory properties. Vitamin E helps support the immune system, cell function, and skin health. It’s an antioxidant, making it effective at combating the effects of free radicals produced by the metabolism of food and toxins in the environment.

Vitamin E is a powerful antioxidant that may be effective at reducing UV damage in skin. And when applied topically may help nourish and protect your skin from damage caused by free radicals.

What It Does

How to use in your skincare routine?

It can be used underneath moisturiser and sunscreen in the morning [if it’s a vitamin E oil] and is sometimes combined with other antioxidants, such as Vitamin C in Serums.

Best suited for those with dry, very dry, or mature skin.

Avoid using if you have very oily, acne prone skin or those prone to sensitivity.

Benefits

In moisturisers it can:

  • Stop skin from losing moisture.
  • Protect cells from damage.
  • Soften skin.
