Cleansing foam that makes acne disappear completely

First off, the product name is Innisfree Bija Trouble Facial Foam. Since it is an Innisfree product, I trusted it and bought it for around 7,000 won per unit during the Olive Young sale. My youngest daughter was so stressed and struggling with acne, so I did a lot of research and bought this for her. After using it for about 3 weeks, all the major breakouts had cleared up, leaving only tiny bumps. The tiny bumps disappeared after using Manyo Factory Houttuynia Cordata Serum. I recommend this to anyone struggling with acne.
