With their tried-and-tested CSA philosophy a hard-working marriage between vitamin C with sunscreen by day, and vitamin A by night Medik8 seeks to create simple routines that result in healthy, beautiful skin for life. The goal is to uncloak the mystery surrounding age-defying skin care with results-driven products that dont compromise on ethics. After creating an anti-redness product for his sister, Medik8s founder Elliot Isaacs fell in love with cosmeceuticals, paving the way for the C-Tetra Eye serum we have today. Its always important to look after the delicate eye area, as its one of the first areas to lose vitality and give way to the classic tell-tale signs of ageing. Thats where the award-winning C-Tetra Eye comes in with a healthy dose of vitamin C and vitamin £ to brighten, smooth and hydrate, this lightweight and fast-drying formula keeps your contours looking and feeling good!
C-Tetra Eye is specially formulated to brighten, hydrate, smooth and rejuvenate, all while preventing free radical damage and reducing irritation. With just two hard-working hero ingredients tetrahexyldecyl ascorbate and vitamin E you can trust this bottled beauty to give results without any alcohol, artificial fragrances or parabens getting in the way of your precious eye contour.
An effective form of the famous vitamin C, tetrahexyldecyl ascorbate penetrates the skins defensivelipid barrier with ease, allowing you to get all of the benefits of vitamin C delivered deep down into the skin. Lightweight and fast-absorbing, the vitamin C in this formula also tackles environmental free radicals by pumping your skin with antioxidants bolstering the defences of your skin cells. This helps to prevent the creation of premature damage - think: fine lines and wrinkles - all while boosting collagen production to make your eyes appear brighter, too. Vitamin E also contains antioxidants, and complements vitamin C perfectly they work together to boost their levels of efficiency, keeping skin protected throughout the day. Name a better duo, well wait! Vitamin E also soothes and nourishes, reducing irritation and revitalising tired eyes. The all-natural, citrusy aroma doesnt hurt, either!
After cleansing in the morning, use the spatula-style applicator to sweep a small amount of C-Tetra Eye across the under-eye and brow bone, avoiding eyelids. Gently blend.

Nice under the eye product
Not irritating, excellent under makeup, and for further layering. Would need to use it a bit more for more solid feedback
Report this reviewGreat
I love this eye serum so much, never used something similar before. It is so smoothing and hydrating
Report this reviewI adore Medik8 products
I adore Medik8 products and this one is not an a exception. I use it in the evening and it really does brighten up and smoothe my under eye area. I will definitely buy again. A little goes a long way.
Report this reviewWell but...
Although I'm liking it, I expected a lot from this product and I think I still need a little more time to use it to see optimal results
Report this reviewThe difference
There is a difference before and after using this serum. My dark circles are brighter and less folds. I highly recommend it.
Report this reviewNice product
It is a nice product, even if it’s an oil, it’s lightweight. The smell it is just awesome, and it absorbs quickly. For my really dry under eye area, it isn’t enough, I have to put a creamy formula afterwards. I haven’t noticed that it has helped to reduce my under eye darkness though.Â
Report this reviewEye Serum
I wanted to try this as it has Vit C and I like to use an eye serum before the eye cream. I must say I like it a lot, absorbes well and keeps eye area hydrated. The spatula initially seems odd but when you learn to use it it’s perfect to get the necessary amount. This really last forever despite the small bottle. I will repurchase
Report this reviewNot for me
I love medik8 so I thought I would give the eye treatment ago despite reviews, but I have to say when it arrived I was shocked! The bottle is tiny anyway an then the product is only filled half way which is really poor in my opinion. The product itself is nice however very hard to apply where the consistency is like water. In my opinion I prefer the feeling of a cream around the eye area.ÂÂ
Report this reviewSo far so good!
I've been using this for a few weeks now. Love the smell and texture of this eye product. Sometimes eye creams can be hard to absorb & pat around the eye area but this serum absorbs so easily. Even though the bottle is small, a little product seems to go a long way. I'm not sure yet if it's actually brightening my eye area in any way but it's definitely hydrating it.The only thing I don't like about this product is the applicator, I just don't get why it has a spatula end with a hole in it?! Surely a pipette dropper would make more sense.
