Reviews

Like it.

"I really like Medik8 C-Tetra. It has a gentle, gradual effect rather than delivering instant results. It’s suitable even for sensitive skin, as it doesn’t sting or cause irritation. A great vitamin C serum for those who prefer a gentle approach to skincare."

— Zhanna K. (5/5)

Visible results and lovely texture

"I really love this serum! I noticed that my pores look smaller and my skin tone has become more even. The texture is lovely — it absorbs very quickly, doesn’t feel heavy or sticky, and layers beautifully under any moisturiser. I’m very happy with the results and will definitely continue using it!"

— Alla B. (5/5)

If you get anything from Medik8 get this !

"This is the best vitamin c serum I've ever used. So gentle on the skin and leaves an unbelievably gorgeous glow on the skin. Feels comfortable and hydrating. If you want to try one product from medik8 let it be this one!"

— Halima M. (5/5)

Amazing product

"Absolutely beautiful product, I love the texture it blends in beautifully and gives my skin hydration, it comes in a darker colour bottle to keep the vitamin c stable, it blends, such a lovely product to use"

— Deborah F. (5/5)

Fantastic Vitamin C ever

"I really like the texture of C-Tetra® Advanced. My skin type is dry combination and the serum does wonder to me and the texture helps drive the serum absorption. I notice that my skin is getting brighter. I am on my second bottle and I use C-Tetra® Advanced every AM, followed by the sunscreen"

— Christine H. (5/5)

Vitamin C without the oily feel

"I tried a sample of C-Tetra Advanced and will definitely buy the full size. I love the texture, I often find vitamin C products too oily for my skin, but this one doesn’t feel oily at all. Such a good match for me, and I’m really glad I got to try it."

Vitamin C Lotion

"So far I have noticed that my skin looks a lot healthier. Dark spots are starting to fade away and skin tone is a lot better. I only wish that this bottle was a lot bigger so I can use more of it. Especially at that high price point."

— Ryan V. (4/5)

10/10

"I love this serum so much. It feels so luxurious on my skin, it’s a pleasure to use and you only need a few drops. My skin looks amazing after using it and it feels so soft. I’ve really noticed my skin has improved in the months I’ve been using it. It’s more glowy and smooth and has a more even tone. I’ve experienced no irritation when using it unlike some other Vit C products and it’s a more stable product in proper packaging so I’m not worried about it going off!"

— Lauren D. (5/5)

Advanced c serum

"I’ve Been a user for medik8 products for over a decade i care about what I put on my skin and I must say It’s one of their best product I’ve ever come across. It doesn’t irritate my skin. Non greasy serum does the job it is made for. it has made a difference to certain areas of my face where the skin tone had become dull those areas have evened out making my skin look refreshed."

— Nusrat B. (5/5)

Great product already so far!

"I have noticed such a difference in the overall brightening in my skin already, I look more even and less dull of a complextion. It’s smooth and sits so nice on my skin. I have yet to see any difference in fading of my minor pigmentation as it’s still such early days but this is what I’m hoping for as I continue to use it. Will definitely re purchase!"

Q&A

I use c extra luxe but looking to move onto advanced and want to check ingredients. I am allergic to polysorbate 80
Hi Frances. C-Tetra Advanced does contain polysorbate, so if you have a known allergy to polysorbates, we wouldn’t recommend switching to this product without first checking with your healthcare professional. We’d also recommend reviewing the full ingredient list and carrying out a patch test before use.
Hi, I’m currently using the C-tetra luxe, is it possible to alternate this with the C-Tetra advanced?
Hi Gill, great question! You certainly could alternate C Tetra Luxe with C Tetra Advanced if you wanted to keep both within your routine.
Can I use these with NIACINAMIDE PEPTIDES?
Hi Jade, yes, Niacinamide Peptides and C Tetra Advanced can be used together. Niacinamide Peptides would be used first as it is water-based.
Can I use this in the evening instead?
Hi Lou, this is a great question! C-Tetra Advanced can be used morning or night, but we recommend using it in the morning to get the most benefit. It’s designed to protect your skin from daily environmental stressors, working alongside sunscreen to form part of our CSA routine: Vitamin C and SPF by day, Vitamin A by night for overnight repair.
Hi, can I use C-Tetra Advanced and Clarity peptides together? In what order?
Hi Victoria, this is a great question! Yes, you can absolutely use both! Apply Clarity Peptides first, then follow with C-Tetra Advanced for best absorption. Together they make a brightening, soothing duo that leaves skin calm and radiant.
