Love this product and so far I haven't found a single Medik8 product I don't like. I started off using this slowly, twice a week and then increasing to every morning. It has a lovely texture and sinks in to the skin well without being too oily. It immediately makes my skin glowy and smells beautiful. I usually leave it to sink in to my skin for around 5 to 20 mins before moving on to my eye cream, moisturiser and sunscreen. Will definitely be repurchasing.

So pleased with all of the medik8 products I have used so far all of them are amazing. C -Tetra makes the skin soft, bright and glowing. Easy to apply, dries and is absorbed quickly. I use this in the morning and my hydra B5 serum in the evening. Medik8 is the best 👌 definitely would recommend all products from the medik8 range.....one very happy customer 😀

Citrus smell is refreshing and serum absorbs into skin quickly for a perfect first layer. I’ve only been using it for a few weeks, but skin definitely looks brighter. Would recommend.

I love this vitamin C product. Its very gentle and nourishing due to the addition of vitamin e. Its been helping my skin with post chickenpox scarring. A holy grail product in my morning routine.
I was recommended this by a beautician who does my facials and it’s a lovely serum, not too heavy and doesn’t need a lot for good coverage. It gives a lovely glow and i’ve noticed a brighter look to my skin! I use this most mornings before my moisturiser and SPF! I would definitely recommend!
Having previously used the c tetra luxe and given that it is an expensive serum I thought I'd give this a try. I'll be honest they both seem to have the same results on my skin. The serum is more like an oil however isn't oily on the skin. Sits well under any moisturiser that I use. I love all of the medik 8 products that I have tried, especially the crystal retinal 6.
I thought I’d try this product after it was recommended to me. I’m 49 and felt my skin looked a bit dull and lack lustre. I’ve been using it daily for nearly two weeks and must admit that my skin looks healthier, more glowing and feels smoother. It’s like skin food and feels like it’s been invigorated. It’s definitely one that I will keep on using and purchasing.
This is my second bottle of C-Tetra and still really enjoying the product. I like the smooth texture and lightweight feel on my skin and glowey complexion after application. The bottle keeps well and has lasted me 3/4 months with everyday use. I have combination skin which is prone to breakouts but have not noticed either an increase or decrease in breakouts since using this product.
I am really enjoying using this serum. Whilst it's oil-based, it is quickly and easily absorbed into the skin and really helps to brighten it; no having to wait around for 15 minutes whilst it sinks in. My skin has a lovely glow after application. It also causes zero irritation to my skin, unlike other vitamin C serums I've tried in the past.
I really like this serum. It is an oil, and it applies nicely. Just drop it into your palm, then rub the palms together then rub your palms on your face. It soaks in well, it doesn't leave my face feeling sticky, and it smells really nicely of oranges. As for results, I think it helps my skin look healthier. I haven't noticed any negative reactions to it. Long-term effects, it's hard to say - I haven't been running a scientific experiment! It feels like my skin is going in the right direction with its help.
