Mung beans are really good for acne (or troubled skin, which Korean brands tend to use) and this cleanser is just great. I have kept away from foaming cleansers because I tended to lean towards dry/combination, but my skin has become more breakout prone, oily and dehydrated in the past few years, so my moisturizing cleansers weren't cutting it anymore. This cleanser lathers up really nicely, so you only need a teeny tiny amount for your whole face. Considering how big the bottle is, it will probably be a year before this is used up. That's pretty good mileage for the 6 bucks I paid. It IS drying though, so stay away if you have dry skin. I cannot use this everyday, especially because it's winter right now, but I do reach for it quite often. My only minor quibble with this is that the lid doesn't actually snap shut, so if you have dried up gunk around the opening it doesn't completely close, and water from your shower can get in it, making it slightly unsanitary. Other than that it's cheap and effective.
