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!"

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)

Gentle, Effective!

"I've been using this for 2-3 weeks so it's difficult to tell how much it's helped, but I do visibly see an improvement in brightness and tone, even in such a short time. My skin is sensitive and this has not caused any issues. It also smells like citrus and not hotdog water!"

Sarah M. (5/5)

Lovely serum

"I haven't been using the C-Tetra Advanced serum for very long, but so far I really like it. I was initially worried because it has a slight citrus fragrance, which I usually avoid. But I haven't had any irritation or adverse reaction. I'm already noticing a glow and a slightly brighter complexion, which I hope will improve with continued use."

Hilda F. (5/5)

Best results ever!!

"Since using this amazing product, my skin has never looked and felt better!… Even though I am 76 years old, I receive more compliments now than when I was in my 40s…. I recommend it to everyone I know."

Johanna M. (5/5)

Best Vitamin C

"This is the first vitamin C I’ve found that doesn’t irritate my skin, and also delivers results. I saw positive changes in my skin quickly, and will continue to purchase this serum as a regular part of my routine."

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.
