Going to be honest here. I purchased this product because Aeri (Giselle of Aespa) promotes this product, and I impulsively got it. Having said that, it really does lather up with just a small amount and it makes your skin feel clean.
The only thing to be aware of, if you don't know how to read Kanji/Hiragana, the back of this product won't make any sense to you! But it is a cleaner. Just put a pea size in your hand and wash your face for ~30 seconds, then rinse with warm water thoroughly. Pat dry with towel.
