Loooove it
It is the best vitamin c serum I’ve ever used, it is on the pricier side but definitely worth it!

Smells good
I used to hate vitamin c products as they often irritate me, smells bad and too oily. This is perfect! Silky texture that’s absorbed into the skin immediately and so good on my skin. Will definitely purchase again and I might try the stronger version

Amazing
I have bought this product time and time again and no other vitamin C I have tried matches up to it. It smells amazing, really moistures the skin and gives you a good glow

Fave vitamin c
My absolute favourite vitamin c serum. I have tried sooo many vitamin c serums from different brands and none of them have really worked for me. Not only does this Vitamin c serum make my skin look brighter but also does not dry out my face like other vitamin c serums have. I think it’s because this is more oil kinder based. This is definitely for the dry skin peeps

Would Recommend
This is the second bottle that I have purchased. Really like this product, it has a slightly oily consistency (which I personally don't mind) but sits really well under moisturiser, SPF and any other products. It's been a really nice addition to my skincare routine and the best Vitamin C that I have tried!

Good but oily
I ordered this product full sized after receiving a sample, really like the product however is quite oily compared to other vitamin c’s I have tried! Nice results in terms of skin brightness however if you have drier skin definitely worth a try!

Go to vit C
Great vitamin c, this is my 4th bottle. It's a bit oily in texture but fine under make up and moisturiser but worth considering if you're oily already.

A fab vitamin c
This was the first oil based vitamin c I’ve used and I really liked it. It absorbs really quickly so it doesn’t leave my skins feeling oily. It works well on top of serum and under moisturiser, spf and makeup. Smells good I had the Sunday Riley oil to try from the cult beauty freebie bag and an upcoming advent calendar but if don’t get on with that I will definitely come back to this as it’s worked really well for me. I haven’t used a medik8 product I haven’t liked.
