Gözle görülür şekilde parlak bir cilt için ultra nazik ve mükemmel

DANIEL ISAACS Ürün Sorumlusu

Zamanla gücünü koruyacak bir C vitamini serumu formüle etmek son derece zordur. Bunun nedeni, C vitamininin bilindiği üzere dengesiz olmasıdır, yani ışık, ısı veya hava ile temas ettiğinde etkinliği tehlikeye girebilir.

Bu nedenle, C-Tetra'yı son derece stabil bir C vitamini formu (tetrahekzildesil askorbat) ile formüle etmeyi seçtik, böylece C vitamininizin ilk kez açtıktan 12 ay sonra bile hala aynı derecede güçlü ve etkili olduğundan emin olabilirsiniz.

Reviews

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)

My only vitamin C serum

"I am using this for over 4 years and don’t want to use any other brands I had used before. This serum works amazingly with dark spot, moisture, truly glows my skin and makes my skin smooth. Sometimes, I only use this serum and sunscreen only without moisturizer. It is no greasy and lasts long with a few drops each day."

An C. (5/5)

Super! really like the Medik8 C-Tetra serum. It has a lightweight texture, absorbs quickly, and gives my skin a healthy glow. After a few weeks, my skin looked brighter, smoother, and more even-toned without any irritation.

Great product. Have been using

"Great product. Have been using for over a month now and my skin feels brighter. It feels and smells super fresh and layers well under my moisturiser. Will definitely be keeping this one as part of my regular skincare routine."

Jocelyn M. (5/5)

Favourite

"I have been using C Tetra for over a year now, I tried another brand but Medik8 is my favourite. You only need 4 drops so the little bottle lasts a long time. Soaks straight in and helps to keep my skin glowing."

Wendy M. (5/5)

C-Tetra

"a fantastic investment for anyone looking to enhance their skincare routine. Its brightening, hydrating, and protective properties make it a must-have. Highly recommended!"

Yvonne B. (5/5)

Pleasant to use and it

"Pleasant to use and it helps even out skin tone well. However, the oil is extremely runny and pours from the dropper like water, making it difficult to control the amount. Honestly, it feels as though the dropper was designed this way so that the product gets used up faster and needs to be repurchased more often."

Elena K. (5/5)

On the fence

"I’m on the fence with this one - I am reintroducing vitamin c to my routine after years of sensitivity/irritation due to rosacea, and this causes zero irritation which is brilliant. This is my first bottle so TBD on longterm effects. However, this just doesn’t sit well under makeup - I am greasy within a few hours, no matter what foundation or how much setting powder I use; add any SPF on top, too, and it’s like a slip n’ slide. I’ve tried different products (medik8 and others) and it’s all the same, with varying levels of shine. Someone help?! Also, the twist topper broke within a few weeks because I tightened it too hard. I’ve never had this happen and for the price, I expect better quality. Probably lessened the efficacy but still using it up anyway in a different container."

Erin (3/5)

The best vitamin C ever

"This has to be my holy grail vitamin C. Although it is oil based, it isn’t oily. It sinks right in, leaves my skin feeling feather soft and provides an immediate glow. I’ve been using this for about 6 weeks now and people have commented on how nice my skin looks."

Ross G. (5/5)

love it, my 10th bottle maybe

"C-Tetra™ is a lovely vitamin C serum that gives my skin a healthy glow and feels gentle enough for daily use. It absorbs quickly, layers well with other products, and leaves my skin looking brighter and more even over time."

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
