One of the Best

I love this, I gave it 3 weeks, since I was wearing 15% ascorbic acid and was kinda sceptical if this will be for me (maybe it was not enough for me) and my face looks amazing with this!! Radiant and so healthy!! I am converted!

the best one s far

I hesitated for a long time about ordering this product (due to the price), but I finally decided to do so, and I have to admit, it was a bull's-eye! I've tried several different vitamin C products (including Medik8 in various concentrations), but this one beats all the others by far. The consistency is perfect; it doesn't roll or stick—perfection.

Love it!

Lovely vitamin C serum. I took a risk buying it because it's expensive and it's also an active that my skin doesn't really tolerate but this one must be formulated in a way that makes it more gentle. So far no breakouts and I've been using it for a few months. I'd recommend this serum more to someone who has dry/combo skin.

GORGEOUS

I can't recommend this serum enough! I used first in the advent calendar! (I sneaked it out cause my DE was finishing) and oh my gosh! Bought another one right away! I get compliments even from my habby who he sees me almost everyday all day, he can even tell the difference! I was used to a 15% potency, but this is a game changer!! But it with closed eyes if your skin can handle it!!
