Reviews

Too oily, but beneficial for neck and chest

"Too oily, too citrussy, I don't get on with this as much as the advanced moisturiser I got in my bundle. For a combination skin it feels too heavy. I way prefer Typology Vic C serum as that is light, higher Vit C content and non fragranced. However, I have taken to using it on neck and chest when the citrus grapefruit smell is welcome in the morning and it is as effective in these areas as This Works neck and chest serum."

This is my first time

"This is my first time of using vitamin c cos I have always been worried I will react to it but with the medik8 no reaction at all, I got this radiant on my face using it. I have now moved on to the advanced one and I can say I’m so happy I started using it. My skin loves it and the glow on my face is top notch."

Hard to pick a favorite.

"This is my first time using the C-Tetra Luxe and I was blown away. I typically use C-Tetra Advanced, which I love, but I was looking for a product with a different texture. This oil is smooth and super hydrating. My skin just glows since using this. Time will tell if it holds up to the Advanced formula but so far I am loving it."

A little bottle of Joy

"I have been using the C-Tetra for 9 months and wanted to try a stronger strength Vit C so bought this travel size. It is easy to dispense with the dropper and absorbs well into my skin. I did a patch test first as I have sensitive skin. I have had no reaction to the stronger strength. My skin has a definite glow without looking greasy and helps to make my skin feel hydrated. Will be purchasing a full size next time."

bien mais pas super adapte pourra peau

"il est tres bien unifie le teint mais j'ai eu une inflammation sur les sillons du cote du nez et une dermite, car le produit est un peu agressif pour ma peu , j'ai du suspendre le tout durant 6 semaine et je l'applique sur les joues front et cou mais plus autour du ne et ni sur la lèvre supérieure"

C-Tetra® Luxe

"I absolutely love C-Tetra® Luxe! It has a beautiful lightweight texture and leaves my skin feeling incredibly soft, smooth and hydrated. My complexion looks brighter and more radiant, and my skin feels healthier and more even with regular use. I also love that it feels luxurious without being heavy or sticky."

Finally! A Vitamin C that doesn't upset my rosacea.

"At 63, with very dry skin and rosacea, I had almost given up on finding a Vitamin C serum. Every other one I tried left my face red, stinging, and irritated. The Medik8 C-Tetra Luxe is the first one that actually works for me. Instead of a harsh liquid, this feels like a rich, comforting facial oil. It sinks right into my dry skin, making it feel instantly hydrated, plump, and smooth. Best of all, it is incredibly gentle—absolutely zero redness or irritation. After using it for a few weeks, my skin looks brighter, healthier, and has a lovely glow. It is definitely on the pricier side, but because it actually delivers results without causing a rosacea flare-up, it is worth every penny. If you have mature, sensitive skin, give this a try!"

— Dawn W. (5/5)

Lovely to use and feels luxurious

"I am really pleased with the C-Tetra Luxe. It is very easy to apply, feels lovely and smooth on my skin, and absorbs nicely without feeling heavy or sticky. I really enjoy using it as part of my skincare routine and my skin feels soft, smooth and well cared for afterwards. A beautiful product that I am very happy to continue using."

— Rahsan E. (5/5)

I've been using this product

"I've been using this product for the past two years and it's amazing. I can see a vast difference to my skin. The application is smooth and leaves a beautiful sheen to the skin leaving it hydrated. I highly recommend this product."

I'm so confused! I just want something to reduce the wrinkles! After using your micellar mousse and then your Press and Glow, I use your Vit C C-Tetra Cream with SPF30, followed by an SPF50 sunscreen and a foundation of SPF30. In the evenings after mousse and toner it's either your Retinol Smoothing Night Cream or Crystal Retinale 3 (I alternate them). Is there anything else I should be doing? I've been reading about CSA, not sure if I should be doing more? I don't have limitless funds, but I want to do what's right for my 64 year old face - preferably whilst there's an offer on!!! Many thanks.
Hi Ruth. You’re actually already very close to a perfect CSA routine. The key now is progression rather than adding lots more steps. We’d recommend gradually working up the Crystal Retinal ladder beyond Retinal 3, as this is where you’ll see the most impact on fine lines and wrinkles over time. If you wanted to add anything extra, Exo-PDRN Prismatic+ is a great supportive step for overall skin quality and rejuvenation, your core routine is already solid.
Hi! Big fan of C-tetra Luxe, but so far I've only used it in my AM routine as my PM routine involves the Retinol 6R and also occasionally an AHA/BHA exfoliation (baby facial by D.E. or the Dennis Gross peels) so I am not sure whether it is ok to also include C-tetra luxe in this routine (I'd love to, hence the ask). Can you please shed light?
Hi there, thanks for your question! We're thrilled to hear your incredible CSA regime. C-Tetra Luxe works best in the morning with SPF as an antioxidant. Keep evenings for retinal and exfoliants so Vitamin A can do its overnight repair.
I have read that grapefruit peel oil is photosensitive and should not be used in daytime products. Then why does c-tetra luxe include grapefruit peel oil? What’s the purpose of adding it?
Hi, in our vitamin C serums the essential oils are used in tiny percentages, just to add a subtle natural aroma to the products. At these low levels the essential oils will not cause phototoxic effects.
Is there a time limit once the bottle is opened to use it within?
Hi Lesley, great question! Once opened, you have 12 months to use this product.
