I think it does its job of cleaning and is not irritating but didn't see brightening effects.
I was lucky enough that @0.8l_usa sent me the Huangjisoo Pure Daily Foaming Cleanser for review! I recieved the Whitening | Brightening version and used it as a 2nd cleanse. I found the smell was a bit strong for me, but in foam form is less noticable. I used 3-4 pumps of the rich foam and massaged it into my wet face. It was super soft and i liked the feeling it left me. It wasn't too drying and my face was very smooth after washing. I didn't notice much whitening or brightening but I think with continued use, its possible. Overall I think its a good cleanser.
