Reviews

Only vitamin c that doesn't break me out

"I was opting out of vitamin C altogether because I could not find one that didn't cause an acne flair up. I LOVE that this is a low dose vitamin C (7%) that doesn't have this effect on me, and feels divine. I love the hydrating lightweight oil that leaves an awesome glow, and that I still get some protection against pollution and free radicals."

Pryscilla B. (5/5)

My skin loves it

"This vitamin C oil is just gorgeous. I tried a vitamin C cream from another brand which was recommended by a friend, however, it turned my nails orange and put me off using Vitamin C products. But I have recently changed most of products to Medik8 and though I would try this C Tetra as it was clear. It soaks in beautifully, my skin looks really good, I am in my late 50s and got told recently I don't look it. My make up goes on better. Will buy again. Oh and no orange nails yay"

Debbie R. (5/5)

Excellent smell, texture and effect on pigmentation

"C-tetra line of Medik8 are fantastic overall. All the products are very good. I used both the C-tetra and c-tetra deluxe. If you want a lighter serum, c-tetra is excellent. If you need a thicker one, deluxe is really good. Both leave your skin very vibrant and smells excellent. It also worked very well on my pigmentation."

Melis S. (5/5)

Great for brightening

"I love this, I have the eye vit c and the face. I like the way it absorbs quickly and easily, no residue. Layers well. I don’t think I’ve been using it a month yet but I’m Pretty sure my eyes are brighter…. . medik8 are defo my very best new favourite skincare all around!!! And I might add- they have the absolute BEST customer service."

Laura B. (5/5)

Amazing!

"love the lightweight consistency, the citrus smell is heavenly compared to other "hot dog water" vitamin c serums scent! It absorbs well on the skin and feels lovely, with a slight bit of slip to the texture but not too much of an oily or silicone-y feel like others. LOVE IT!"

Melissa W. (5/5)

Ninguna mejoría.

"No he notado absolutamente ninguna mejoría en mi piel. Arrepentida de haber invertido dinero, que no es poco, en este producto. Ya me gustaría estar diciendo lo contrario, pero la realidad es esta."

Blanca C. (2/5)

Loving it

"I am so glad I received a sample of C-Tetra otherwise I would not have purchased it. I am seeing great results in my skin using this in my AM routine and your Retinal in my PM routine. This is a new regular for me."

Lori B. (5/5)

Amazing

"I have ultra sensitive skin and have had bad experiences in the past with vitamin c (acne, damage to skin barrier). This serum is so gentle and provides incredible results. My skin looks more even, bright, and luminous after using this for only 3 weeks."

Tavish B. (5/5)

Broken Bottle - the top squeeze part came away from the lid

"I loved the product - however I was only able to use it for approx a week due to the bottle breaking and the entire bottle emptying out into my make up bag - so I feel I wasn't able to get a proper testing of the product. However what I did love was the feel of it - it applied to my skin so smoothly and smelt amazing!"

Kelly F. (5/5)

C-tetra

"With this product I always asks questions on its benefits for anti aging. I personally use medik8 products that show such improvements on my skin. Still trying to decide if I would purchase again guess I need to keep using it."

Q&A

Good day! In the morning routine I want to use C-Tetra Lipid serum and Clarity Peptides Serum. How to use correctly then or may be not mix them at all?
Hi Halyna, you can absolutely use them together in your morning routine.Apply C-Tetra Lipid serum first, then follow with Clarity Peptides Serum. Finish with your moisturiser and SPF. That order will give you the best absorption and results
Hi there, can you use the C-Tetra with the Hyrd8 B5? If so, which should go on first? Thanks.
Hi Emma, thank you for your question! Yes, you can absolutely apply the Hydr8 B5 serum, before your C-Tetra serum to provide your skin with an extra boost of hydration. This layering ensures your skin stays hydrated while reaping the benefits of vitamin C. Thanks, Medik8 Team
How much C-Tetra should Ii use (I put it on in the morning after cleansing and before moisturiser)? It says the bottle should last up to 6 months but mine lasts about 6 weeks (full size) so I'm wondering if I'm using too much?
Hi Jane, thanks for your question about our C-Tetra! For best results, we recommend around 4-6 drops applied to the face, neck and decolletage (avoiding the eye area directly) and slightly less if you aren't applying to the decolletage for example. Each bottle when used as directed contains up to 200 applications. We hope this helps! Thanks, Medik8.
Для якого віку ця сироватка?
Hello, Thanks for your question. Our C-tetra serum is suitable for age 16 and up. Thanks, Medik8 Team
When do I use this when using with liquid peptides?
Hi Olivia, thanks for your question - for best results, apply Liquid Peptides before C-Tetra. Thanks, Medik8 Team
