## Description

COSRX The Vitamin C 23 Serum 20ml

Review: Great for resilient skin girlies :) - I love the glowy effect this serum gives and it also brings radiance and lightens pigmentation with consistent use. It doesn't irritate my skin at all (individual results vary) and is really niceee :) so if you are wondering whether you should buy it or not, YES YES YES. It's nice. You might take time to adjust to smell but after a few days you won't even feel it. Just store it in a cool, dark, dry place cz it's potent pure ascorbic acid. And also your skin can be irritated so be careful if Ur skin is ultra sensitive. Overall it's a great bang for your buck✨☕🧴

### ⭐⭐⭐⭐ Pro - Pure form of Vitamin C, Con- horrible smell (Pure vit c smells like rotten sausage)
*by O***I on 18 November 2023*

I couldnt use this product at all, it has a horribe smell... It smelss like a rotten hotdog, made me puke... I understand this is the purest form of Vitamin C and may work if i had used it, but its a no no for me. I cant withstand the smell On potency, i cant review because i only used once but i guess it should work since its in a pure form.
