Love it
Love what it does and the way it smells. Only criticism is that sometimes I doesn’t sit well under make up

Use every day...
I bought the C-Tretra because I couldn't afford the C-Tretra Luxe this time. You get what you pay for - amazing product, but I'll def try and get the Luxe next time – the glow and moisturising quality lasts so much longer. Both still top products.

Best Vit C Serum
This Vitamin C serum has a lovely texture & is not irritable to the skin. It has helped clear the pigmentation marks on my face and my skin is glowing. I used to use Obagi but have had better results from this product which is considerably cheaper. I would definitely buy it again. 5*

Medik8 c-tetra serum
I've been using the serum for almost 3 weeks and so far so good! No huge change in the appearance of my skin yet but I've olny been using it once a day for a short time. My skin looks less dull and it hasn't irritated my skin at all (I have sensitive skin and rosacea). Only con I'd say it it can feel a little greasy on the skin which is why I'm just using at night at the moment but it might just be my skin!

The best
This was recommended to me by my aesthetician. I had used it before and loved it but thought there might be something similar for a cheaper price. I was wrong. This is really good

Amazing serum
I love this vitamin C serum. It has a silky texture and gets absorbed quickly into the skin, making it more radiant. It's great that it contains the Tetrahexyldecyl form of Vitamin c, which is much more stable in formulation. The only minus is that it has a pipette, rather than a pump, which means that the serum can oxidise quicker and lose its properties - so try not to leave it open for too long.

Love it!
Bought this twice. Works wonders overtime. My skin has cleared. Feels soft, radiant and brighter. Reduces the appearance of hyperpigmentation. Would recommend.

Brilliant vitamin c serum
Works perfectly for all skin types - it isn’t greasy on oily skin and won’t cause breakouts. It’s also gentle enough for a first time user. I managed to get my husband using it - he even got himself a new bottle when he finished it!

Great
This is my second time buying this serum. I’ve been using it for almost a year and it’s the best I’ve found so far for the price. You only need a few drops and it lasts a long time. There is a nice clean smell when first applying but quickly goes away. I use it everyday under sunscreen and I have been getting more compliments on my skin looking brighter.
