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✨☕🧴

I like this serum it is very good for my face

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.

I hate the smell of this product. The product description says unscented but it smells like bbq chicken or oil from chicken fat. It also left my skin dry. I still have more than half a bottle left but cannot stand putting it on my face and getting that fried chicken smell. So weird

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 product But scent is lil bit disgusting

Very good

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.

脂性敏感肌です。リニューアル前のと比べると圧倒的に使いやすくなりました！！（匂いや使用感）肌が敏感になっている時は、ピリピリするので塗布する量や肌の状態に気をつけた方がいと思います！！！1〜2滴だとベタベタするのと匂いが少しあった。ベタつきが気になったので、0.5くらいの少量だけ塗ることにしました！匂いもZEROではない！ 毛穴が小さくなったり、肌が明るくなる！という目に見えた効果は私は感じられませんが、未来の肌への投資ということで使い続けています✌🏻( ᵔᢦᵔ )5本以上リニューアル前から使ってます（肌が薄い方や体質の方は感じられると思います）

its kinda of sticky, but it does good to my skin. I dont rub it but just tap it to my face, every other day.

Very good product well worth the money and very fast delivery

بنات ما يسوى ابدا تاخذون شي مو موثوق لانه رخيص وتعالجون بشرتكم لشهور اولا ريحته كريهة جدا كانها ريحة فاصوليا معلبة بدون مبالغة وهذا الشي كان ممكن يكون محتمل لو انه منتج فعال سبب لي حبوب حمراء اول مره اشوفها بوجهي وقعدت اعالجها لفترة، بشرتي دهنية طبعا استخدمت تونر من نفس الشركة وبرضو ماهو احسن منه، بس متأكدة ان هذا السيروم سبب الحبوب لاني حسيت الحبوب خفت بعد ما وقفته حتى مع استمراري على التونر كان يحرق كمان مع اني سويت اختبار على رقبتي وقلت ممكن طبيعي بما انه فيتامين سي انا ما اعرف اذا المنتج مو اصلي او مكوناته ما ناسبتني بس عموما ما يسوى تعيشين بهالقلق بعدوا عنه احسن

I have been using the COSRX Pure Vitamin C Serum with Vitamin E for a while now and I really love it. At first, I noticed it has a slightly weird smell. It is not unpleasant but definitely unique compared to other serums I have tried. Once you get used to the smell, it is no longer a problem. What I really like is how it feels on the skin. The texture is very lightweight and it absorbs quickly without leaving any sticky or greasy feeling. It gives my skin a fresh and real sensation as if it is doing something beneficial deep down rather than just sitting on the surface. Since using this serum regularly I have noticed that my skin looks brighter and more even toned. It feels softer and smoother. The added Vitamin E helps with hydration and nourishes my skin. I also appreciate that it does not irritate my skin even though it can be sensitive sometimes so it is gentle yet effective. Overall despite the odd smell at first the performance of this serum makes it totally worth it. It feels like a high quality product that works well and I would definitely recommend it to anyone looking to improve their skincare routine with a Vitamin C serum that actually delivers results.
