Unveil a visibly brighter, energised and smoother-looking eye area every morning with this innovative vitamin C eye serum from Medik8.

Expertly formulated with the age-defying powers of Medik8’s C-Tetra face serums, C-Tetra Eye is incredibly lightweight, fast-absorbing and gentle enough to be used around the delicate eye area.

Featuring stabilised tetrahexyldecyl ascorbate, this eye-specialist vitamin C serum visibly brightens and deeply nourishes the eye area, while working to smooth the appearance of fine lines and wrinkles for a revitalised and re-energised appearance.

Key Benefits:
Fine Line Reduction
Smooths the appearance of fine lines and wrinkles around the eyes for a visibly firmer, more youthful-looking eye area.

Visibly Brighter & Awakened Eye Area
Works to visibly brighten the skin tone, improving the look of discolouration and under eye darkness.

Vitamin C Power For Delicate Eyes
The stable formula delivers all of the renowned brightening, smoothing and antioxidant benefits of vitamin C while being lightweight and gentle enough for the delicate eye area.

Key Ingredients:
3% Stabilised Vitamin C (tetrahexyldecyl ascorbate)
This stable, low-irritation form of vitamin C is incredibly effective on the skin; delivering exceptional protection against ageing free radicals. Supporting collagen production and brightening the skin tone, it leaves the complexion visibly more even, radiant and youthful-looking.

Vitamin E
Rich in antioxidants, vitamin E helps to protect the skin against ageing free radicals. It also helps to boost the power of vitamin C for maximum visible results.

Rated 5 out of 5 by from Love this product! Never used Love this product! Never used vitamin c on my skin before. Under eyes feel brighter and I have definitely noticed my skin getting smoother. I don’t get on with the spatula provided, I just use my finger. I initially thought that it was too oily, but it absorbs into my skin amazingly. Highly recommended
