So far it’s the best Vitamin C I’ve tried (and I tried a lot). Been using it just for 2 weeks and already see results. It absorbs really fast and doesn’t feel sticky on your skin at all. The bottle itself is very dark to protect Vitamin from oxidising.

I love love love love.

I love love love love.

This vitamin C serum is great, it is concentrated and adviced for ladies who are 35 and above, and be careful you must follow with sunscreen after applying any vitamin C serum

One of my fave products. Love it so much

Great formulation - it’s a high percentage vit C but didn’t cause me any irritation like most Vit c serums do. It’s like a dry oil serum and sinks into the skin easily. Great at evening our skin tone and brightens skin

Very very very very Very very very very Very very very very Very very very very Very very very very good

I liked it. This product is very good. would recommend.

Really good Vit C product - it’s an oily serum but applies and absorbs into the skin quickly. A little goes a long way and found this brightened and evened out skin tone after a week or two of consistent morning use in the morning. I thought the high percentage of Vit C may cause irritation, but it was really gentle and overall a great product from cosRx. I have purchased again.

I use this in the morning. I notice my face was brighter after a couple of use.

So I'm on my second bottle. It's 20 ml, so it's not a lot of product but my first bottle lasted me over 2 1/2 months. It's not greasy at all. It spreads across the face really well. I also didn't find this to be harsh at all. My skin does appear to be a little brighter. Hopefully with more consistency I'll continue to see better results.

I hope this vitamin c works with my skin. Will update after use.

The best of the best! I really like it and will recommend to my friend ♥️

good product not regret purchasing at all. love it

Works well, but doesn’t smell good. Will not buy again.

Good result after use 2 weeks, will buy second bottle.

It's an amazing product! I recommend it!

I just bought it for my mom This item is kinda expensive when you compare to the size, but they are good.

Best serum, I ordered alot! I am gonna share it with my mom. She love korean brand skincare items!

brightening, very moisturizing and easily absorbed into skin, feels light, not heavy at all

I have been a big fan of all cosrx line but this vitamin c serum is the BOMB

My first vitamin C dedicated serum, love how i can pair it with other products and it doesn’t irritate or sting my akin

Tried many Vit c from ordinary to Paula’s choice, etc but love love this since It launched from COSRX! It has hyaluronic acid already so didn’t need to think which one should go first.. get yours now!

Love it sooooo muchhhhhhhh.
