very good (but beware of its smell)

The smell is so horrible and also I feel that the product sting my face. But, it only lasted for a couple minutes. 

From what I saw after using it for a couple of times, this product can reduce my acne. The redness is still there, maybe I should use another product to treat it (like Vitamin C).

I only use it at night because of the horrible smell haha.

Amazing!

This stuff is AMAZING. I've only used it twice, and my breakouts have gotten smaller, not come back, and my skin is so much clearer. It's insane! I love it! 

Expecting tomorrow!
If I could, I would definitely give this product thousands of stars. I consider this product as the "right hand" of the Cosrx bha blackhead power liquid. They truly compliment each other which makes them both really effective and gives noticeable result in just a short period of time. Recommend, recommend and recommend!!!

Very good!

This is perfect for pimples. It stings a bit when you apply it but in the morning the pimples are smaller and less red. It works really well and I love it. You also don't need a lot so it last long. 

Good
I think it has helped overall with controlling breakouts. It does have a pretty horrible smell, but you get used to it
