So i've been using this for a while. Even though it's cheap doesn't mean it's not okay. It just suitable for me. My skin type is oily type. After washing my face using this Nano White Fresh Foam Cleanser , it doesn't leave my skin tight and dry. different people have different type of skin. So just give it a try ;)

It removes the oil on my face, it freshen up my skin.
I always use it once in the morning, once before sleep.
It help me with my oil, thus reduce my acne because my biggest problem is when my face became oily and it become acne-prone.
It's effective on my combination skin type.
In my experience, it took effect after a month or two.
It does not react badly to my skin, I think it just remove the oil mostly but if wears when dry skin. I would feel a bit irritated around that dry skin area.

i had been using this product from 2015 and i never change it to another cleasers, because this one fit me perfectly, event though nano white fresh claims that this product is formulated for the oily skin, but me the 'DRY SKIN' type still can use this and works amazingly! the ingredients also give benefits to the dry skin person. so i highly recommend this product to those who wants to try !
