Potent but affective

My beautician recommended that I start to use a Vitamin C serum to brighten up my skin.  this product is quite potent, and I was advised to definitely ease into the product especially if you're like me, my skin is quite sensitive and isn’t used to stronger actives. It felt bit intense at first- Fair warning -the smell can be a bit funky compared to other skin care products, but "that’s just the nature of a high-concentration Vitamin C".

Didn’t work for me

This broke me out really bad I don’t know why or how but I had acne like spots that I never really get - went away when i stopped using it. Real shame because I love cosrx things

Really good product

Bottle looks very lux. Smells little bit weird but it is okey. Feels nice on my skin and absorbs very quickly.

Wait and see!

I’ve been waiting for this to come back in stock and i jumped at the chance when I got the notification! I’ve been wanting to try this for ages. I love cosrx products, but my skin seems to dislike vitamin c. I wanted to give this a try. First impressions, the smell is awful! BUT, I’ve only had a little bit of redness, so far no other irritations. I leave it in the fridge as per recommended on the box. Fingers crossed I’ve found a vitamin c for very sensitive skin!
