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.

Love this Vit C serum!
This is my second bottle now! I stopped using it after my first bottle finished as I didn’t realise how much of an impact it was having. My skin was a lot brighter when I used this everyday and over time I noticed a difference in my complexion looking more even. The smell is uplifting and I don’t find it too overpowering. The same applies for the texture, it goes on smoothly and feels light on the skin without feeling like it does nothing. I now regard this as a vital part of my skin routine and wouldn’t be without it.

Love this Vit C serum!
This is my second bottle now! I stopped using it after my first bottle finished as I didn’t realise how much of an impact it was having. My skin was a lot brighter and even when I used this everyday. Love using it before I wear a lighter foundation and it always helps keep my skin healthy!

Glowy skin
Smells divine. Leaves skin feeling hydrated and with a lovely glow. A lovely step in my skin care routine, just before I apply my moisturiser.

Sadly silicone based
Sadly silicone based serum, meaning that it does nothing but creates illusion of skin getting better for a few days while it plugs pores, wrinkles and fakes better skin...
