## Description

COSRX The Vitamin C 23 Serum 20ml

Review: Good - I like it and I have seen results with it quite fast. I liked that it is 23% pure vitamin C (ascorbic acid) and also has niacinamide, hyaluronic acid, and vitamin E. Quite a potent serum and covers all the grounds for you. One thing I didn't like about it is that it oxidizes rather quickly so it is better to keep it in the fridge so it lasts longer. If it is your first time using vitamin C serums then this concentration could be slightly irritating for you.
Review: Amazing - One of the best Vitamin C i have used so far. Even though it has weird smell but its so good on the skin. Just amazing

### ⭐⭐⭐⭐ 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.
