Works but break out at first
I’ve found with a few medik8 products my skin has an adjustment period to them but once that’s happened they work great! I’ve had 3 spots from this but I think it’s because it’s a cosmeceutical product

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.

Expensive but lasts
This took over a year for me to finish, so overall happy with the price. I can’t say I’ve noticed the biggest difference even after using it for so long

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
