No more T zone sheen
[This review was collected as part of a promotion.] I have been using this product now for 5 months. I no longer wake up to an oily T zone and my make up stays where it should during the day. I have far less/severe breakouts and my pores are visually clearer. It also gives my skin a lovely healthy glow. It's an important part of my skincare routine.

poor minimising serum
[This review was collected as part of a promotion.] I have gone through 2 bottles of this one. I do think it helps to some extent but it is not one of my 5 star Medik8 products. It can definitely work better/harder and this is the only bottle where I have a lot of problems with the pump just shooting the serum out so it lands all over my bathroom. This has been with both bottles and never happened with any of my other various serum pump bottles that I have gone through (at least 10 inanition to these two).

I’ve only been using this
I’ve only been using this a few weeks but am enjoying the product, it gives a nice texture to my skin. My only criticism of this is the pump, even if you try to press it down gently the product shoots out everywhere which is a waste.

Great for plumpness and reducing redness
[This review was collected as part of a promotion.] I love this serum for my sensitive and red skin - plumps up immediately, and long term I can see the texture and redness improving. It's a 'trust the process' product, but with some nice immediate effects too!

Effective redness reduction!
[This review was collected as part of a promotion.] I've seen a noticeable difference in redness as well as my pore depth and sebaceous filaments, especially when using this alongside Press and Clear. Will definitely continue using.

A lovely cream feeling serum
[This review was collected as part of a promotion.] A lovely cream feeling serum which has helped improve my skin massively. Definitely part of my daily routine. Dries down lovely and makes my skin feel smooth. Can see a boost in my pores being minimised.

Great product that I have
[This review was collected as part of a promotion.] Great product that I have purchased numerous times now since launched, I get comments on my skin when using it so try now to not run out of it, I notice a difference myself too and use it daily after my vitamin C serum.
