COSRX The Vitamin C 23 Serum 20ml

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✨☕🧴

Very good

I've been using this for a couple of weeks and have noticed slight results, will definitely keep using it, it's great for my sensitive skin, BUT be warned it does smell like hot dog water hehe. but the smell does go away

I purchased this product based on the positive reviews, but when I opened the bottle, it released pressure and emitted a strong, unpleasant odor. I’m concerned that the serum may be spoiled or unsafe to use

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.

Really a good productBut scent is lil bit disgusting

Nice

The high concentration scared me especially since this is my first time using vitamin C but it did not irritate my skin at all. It’s been almost 2 weeks and I can already see my acne scars have faded 55% of the way! It’s really good to use in the daytime as it prevents skin pollution too, pretty hydrating as well as my dry-combo skin has no problem with it.
