My daily serum for vitamin C i love it so nice for skin

I have an oily acne-prone skin and i've tried alot of vitamin c's and it broke me out but this one omg it was gentle on my skin and i saw a result on my post acne marks so quickly ( i pair it with the 6 peptide skin booster serum)..

This has a really funky smell and also hisses everytime I open it. I was concerned at first but after googling it, apparently that is totally normal. So don't be alarmed if the bottle is gassy and smells bad to boot, the smell doesn't really linger and it really is a lovely vitamin C product. It feels lightweight with no irritation whatsoever, my marks are fading faster than ever with this!

best best best vitamin C product out there ..

I was looking for something that could help even out my skin tone on my face. I can already not some differences on my face and I’ve openly been using this product for about 3 weeks. My skin feels smoother and it looks brighter. I use this in the AM and replace my toner with this serum. It truly made a difference in the areas where I had acne scaring and dark spots by minimizing those areas. I recommend if you have sensitive skin.

Slow results showing but still okay

I like this serum. Good quality

Good product.. this is my 1 st order

It’s one of my favorite serum from Cosrx

Best products thank you and i will order again

fast results with this vitamin c, my skin brightens up and pigmentation fades quickly when i use this.

حلوو يخفف من اثار حب الشباب والبقع الداكنة في البشرة

It’s nice and light. I don’t see a crazy difference so far but I only use it a few times a week. It must be kept in the fridge and has a smell. It absorbs quickly in the skin and doesn’t leave it sticky or excessively sensitive.

I don’t know if there’s a difference but leaves my skin soooo smooth in the morning

cosrx-the-vitamin-c-23-serum Is my 3rd purchase.. its an excellent product

I’m repurchasing this product, I love it

I appreciate the thoughtful packaging (separated dropper and bottle) to avoid oxidation. Can never go wrong with COSRX

The best serum to remove hyperpigmentation but it’s very sticky
