This cleanser is very gentle on the skin. It doesn't have an overwhelming smell to it which I also like. I am in love with COSRX!! Every product I have bought so far of this brand I have not at all been disappointed by. This may sound like a sales pitch or something, but it's not. COSRX is honestly one of my favorite skincare brands

I just needed a little amount (smaller than a pea size) then it created a good foam when mixed with water. 

Smells like tea tree.

Feels fresh after wash.

150ml will go a long way.

For these reasons I absolutely recommend this. GOOD BUY!
