Fantastic
Love this product, really smooths and brightens my skin. You can feel the difference from the very first time you start using it. Love the way it absorbs and doesn’t leave you feeling sticky. My only gripe is I probably waist product as it’s so runny.

Great intro to vit c
One of my first vitamin c products and I still love the smell and feel. My skin can tolerate stronger and better products now but this is a good intro

Amazing product
I introduced this in to my skin routine by a friends recommendation and now I couldn’t go back! I love the whole Medik8 range.

Nourishing
Feels great on my skin. The only negative is the drops fall out of the dropper without having to squeeze the bulp so it's a race to get to product from the bottle to your face without it falling onto the table. It doesn't sting or irritate like some other vit c products

Great serum
I've tried a few different vitamin c serums and this is by far my favourite. It sinks in well and leaves my skin feeling great. It is expensive though so unfortunately won't purchase very often.

Smells absolutely amazing.
Love the smell. I’ve only used for a couple of weeks so I can’t wait to see the results.

Not much difference.
I didn’t see major difference in my hyperpigmentation and the bottle is just too small
