Amazing
My skin has never looked better. I was using DE Vitamin C serum before. The difference between this and the DE serum is night and day. Will definitely repurchase.

Dry skin favourite
I have really dry skin and this serum straight out of the shower is amazing at keeping all the moisture locked-in although sometimes I layer it on top of my PSA Skin The Most serum for extra hydration. It's been 2 months and I've received compliments on how fresh and luminous I looked even on days running on 4 hours of sleep!

Repeat purchase
Definitely my favourite vitamin c serum. I usually get fed up of a product by the time I get to the end of it but not with this one. Sinks into my skin easily.

Not absorbent at all
This may be a great product but I had to give up on it and order something else as it didn’t sink into my skin at all. It felt quite nice on and smelt good but just sat on top of my skin as an oily layer. Disappointing as it was an expensive punt on my part.

Too greasy for oily skins
I tried using this product but I found it to be too greasy to layer underneath my usual skincare routine in the morning. I would find my skin looked very oily and makeup didn't layer well over it.

best vit c
I have tried many others but this is the best- great for sensitive skin. Its an oil but is incredibly lightweight and gentle and sinks in straight away.
