Reviews

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!"

Smooth, hydrated, and refreshed skin

"I’ve been using the C-Tetra® Advanced serum and I’m really pleased with the results. It has a lightweight texture, absorbs quickly, and leaves my skin feeling smooth, hydrated, and refreshed without any greasy residue. My complexion looks brighter and more even, and my skin has a healthy glow. It’s also easy to use as part of my daily skincare routine. A lovely product that I would happily recommend."

C-Tetra Advanced Gel

"I really like C-Tetra Advanced Gel! It has a lovely lightweight texture, absorbs quickly, and doesn’t leave any sticky feeling. My skin looks smoother, fresher, and more radiant after using it. It feels very comfortable on the skin and fits perfectly into my daily skincare routine. A great vitamin C product that I would definitely recommend!"

I love the light oil

"I love the light oil texture of the C-Tetra Lux, but it makes my sunscreen pill so I thought I'd try the C-Tetra Advanced. The C-Tetra Advanced is very nice. The light and smooth texture is easy to control for application,. I apply one pump on my index and middle fingers, dot it over my face and neck, and then rub it in. It spreads wonderfully. I recommend."

Vitamine C bon pour ma peau

"Ce sérum à la vitamine C sent l'orange dès la première application. Pénètre rapidement sur ma peau tout en laissant une sensation d'hydratation instantanée. Deux semaines d'utilisation, mon visage est éclatant, ma peau est plus douce. Je l'utilise à chaque jour sous mon maquillage."

CTetra advanced.

"I have been using c Tetra advanced for a few weeks now. I apply it every morning after the peptides. They work well together. The c Tetra smells lovely a little bit like oranges, feels smooth on my skin and absorbs well without leaving it sticky. My skin definitely looks smoother and more hydrated. I can't be without my CTetra."

Favourite product

"My absolute favourite medik8 product. Been using it since I received a sample over a year ago now. It’s luxurious to use, lovely texture, consistency and very hydrating My skin is more smooth and radiant. Looks like I have primer on when i havnt so often just add daily moisturiser and leave it at that!"

C Tetra

"J’aime beaucoup ce sérum : sa texture est très agréable et son parfum léger. Je ne peux pas encore me prononcer sur les résultats, car je ne l’utilise que depuis trois semaines, mais au vu de sa composition, je ne doute pas de son efficacité. Mes premières impressions sont donc très positives."

— Martine S. (5/5)

This C is amazing!

"The texture and application is to die for. There is a slight citrus smell but nothing too heavy. It makes my skin feel fantastic. It has helped tremendously with brightening. I am a freckled mess in the summer and it’s definitely helping with that issue!!"

— Monica M. (5/5)

Une excellent sérum, hyper agréable et qui sent super bon !

"Je cherchais un sérum à la vitamine C à la fois efficace et qui se conserve longtemps. J'avais besoin de changer ma routine à l'approche de mes 44 ans, en optant pour des produits plus efficaces mais aussi plus pratiques, et les sérums Medik8 se conservent longtemps : ce sérum dure 12 mois après ouverture. Ca simplifie ma routine. Je l'applique avant celui aux peptides. Il est non seulement efficace - ma peau est hyper douce -, mais en plus il sent hyper bon ! J'avais peur parce qu'il contenait du parfum mais c'est en fait un parfum naturel, liés aux ingrédients. Ca rend l'application très très agréable. Le sérum est aussi hyper doux pour la peau, et j'ai une peau assez réactive. Pour moi, il coche toutes les cases."

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.
