A great vitamin C serum
Another great product from Medik8! This serum has a great smell (unlike lots of other vitamin C products I have tried), almost has a slightly oily texture, but it soaks into the skin beautifully. No issues with layering with other products.

Love this!
Love this product, and it smells devine! I use in the morning after cleansing and before moisturiser/spf. The bottle lasts a long time too.

C-tetra
I’ve used this a while and like it. However, it comes out really fast and in large volumes. Quite heavy and takes a while to settle. I’ve used various VitC’s and this one is good, just not great.

Worth the money!
This serum is amazing. I have been using it for years. It makes your skin feel so fresh after use. I notice a difference when I don’t use it when I’ve ran out. I would recommend.

C Tetra - Love it!
I have tried numerous Vitamin C serums but always tend to come back to this one. It is a very light oil serum which sinks straight into the skin leaving a lovely glow and the skin hydrated. It has definitely improved my skin tone and I wouldn’t be without it in my routine

So glowy!
I have wanted to add this product to my routine for quite a while, but was concerned with it being on the oily side (I didn't want to set my skin back to breaking out). I have used it for 4 mornings now, both with and without makeup and I can honestly say my skin is glowing. I have been using Medik8 blemish control pads which have worked wonders for me, but this serum has definitely taken it to the next level. It does feel oily initially, but soon works into the skin. I do find the dropper pipette difficult though, the serum just seems to leak out so I have to be quick or I loose some!

Perfect lightweight serum
I initially thought the serum was going to be oily as it’s not gloopy like some serums. It’s not though. It’s super light and quick absorbing. Love it!

Best Vitamin c product I have used
I love the smell so much for a start. The consistency is absorbed into your skin so easily and it feels so smooth once you have used it. I have used the higher concentrations but I like this just as much and it saves money
