Restore radiance and fight visible signs of ageing with C-Tetra® , a super-light daily vitamin C serum. Antioxidant power is provided through vitamin C and E. Together, these actives help to combat sun and pollution-induced damage. The lightweight, uplifting formula helps reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing skin tone. Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra® has been carefully crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop.

Formulated with nourishing, pampering oils combined with the anti-ageing power of vitamin C, this fast-absorbing vitamin C serum is ideal for those looking for skin rejuvenation. Perfect for those who are new to vitamin C, or are looking to upgrade from C-Tetra® Cream or Daily Radiance Vitamin C™.

  • Brightens and restores radiance
  • Fights and repairs free radical damage
  • Hydrates and smoothes skin
  • Promotes collagen and elastin production
  • Leaves skin soft, plump and radiant

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

Healthy Glow

I thought Id try this product after it was recommended to me. Im 49 and felt my skin looked a bit dull and lack lustre. Ive been using it daily for nearly two weeks and must admit that my skin looks healthier, more glowing and feels smoother. Its like skin food and feels like its been invigorated. Its definitely one that I will keep on using and purchasing.

Loving the Glow

I've been using Medik8 C-Tetra® Serum for a few weeks, and it’s already a must-have in my routine. It’s lightweight, absorbs quickly, and leaves my skin looking brighter and more even-toned. The subtle glow it gives is fantastic, and it layers perfectly under my moisturizer. If you're after a Vitamin C serum that’s effective and easy to use, this is it!

Medik8 C-Tetra

Discovered Medik8 this year and this is now one of my go to products. I am now on my second bottle and my skin looks so bright and fresh. I believe that it is helping with the sun damage to my face and will keep using it, maybe switch up to the stronger formula on the next bottle.

Love this product

I started off using this slowly, twice a week and then increasing to every morning. It has a lovely texture and sinks in to the skin well without being too oily. It immediately makes my skin glowy and smells beautiful. I usually leave it to sink in to my skin for around 5 to 20 mins before moving on to my eye cream, moisturiser and sunscreen. Will definitely be repurchasing.

Great serum

Having previously used the c tetra luxe and given that it is an expensive serum I thought I'd give this a try. I'll be honest they both seem to have the same results on my skin. The serum is more like an oil however isn't oily on the skin. Sits well under any moisturiser that I use. I love all of the medik 8 products that I have tried, especially the crystal retinal 6.

Love this one

Been using consistently for over 2 years and can definitely see an improvement. Reduced pigmentation and improved texture plus more hydrated skin.

Quality Vitamin-C serum

I really like this serum. It is an oil, and it applies nicely. Just drop it into your palm, then rub the palms together then rub your palms on your face. It soaks in well, it doesn't leave my face feeling sticky, and it smells really nicely of oranges. As for results, I think it helps my skin look healthier. I haven't noticed any negative reactions to it. Long-term effects, it's hard to say - I haven't been running a scientific experiment! It feels like my skin is going in the right direction with its help.

Love it

My skin is so hydrated, glowing and healthy! It took a few days to get used to the texture but now I can't leave the house without putting vitamin C on my skin. Nice smell as well!

Lovely serum that brightens skin

I am really enjoying using this serum. Whilst it's oil-based, it is quickly and easily absorbed into the skin and really helps to brighten it; no having to wait around for 15 minutes whilst it sinks in. My skin has a lovely glow after application. It also causes zero irritation to my skin, unlike other vitamin C serums I've tried in the past.

Brilliant

So pleased with all of the medik8 products I have used so far all of them are amazing. C -Tetra makes the skin soft, bright and glowing. Easy to apply, dries and is absorbed quickly. I use this in the morning and my hydra B5 serum in the evening. Medik8 is the best ?? definitely would recommend all products from the medik8 range.....one very happy customer ??

Medik8 C-Tetra

Just ordered my second bottle of this and i wouldn't use another vitamin c product now. I may switch to a stronger verson of the C Tetra in the future ut for now this suits my needs and gives me the results i need and i'm happy with. I'm almost 51 and my skin looks younger than it did befopre i srarted using this. Bonus is that it smells divine.

Lovely fresh citrus fragrance, sinks into the skin easily. Am using it as part of Medik8's ASC routine, and am hoping for good results. Bit too soon to tell yet but so far so good. Recommended x

Lovely product

This is my second bottle of C-Tetra and still really enjoying the product. I like the smooth texture and lightweight feel on my skin and glowey complexion after application. The bottle keeps well and has lasted me 3/4 months with everyday use. I have combination skin which is prone to breakouts but have not noticed either an increase or decrease in breakouts since using this product.
