Works well
COSRX BHA gave me chemical burn, so I did not have high hopes for COSRX AHA. To my surprise, I find it quite gentle and it clears most of my white head.

liquid

This did not work well for me as i have very stubborn whiteheads maybe it would work on others.

Smooth skin

Helps my skin bee smooth. Use with caution not to overexfoliate and always use sunscreen.
 

good

I love it. Not so expensive as well!!! :) :P 

Not convinced yet

I purchased this AHA because many people said it made their skin very smooth. Well, in my case, it does get rid of some dead skin cells, but a few dry patches still remain present. However, I have noticed that it works really well if you put it directly on the breakouts! Oh, and it performs wonderfully when it comes to treating body acne.
