Gentle, mildly acidic cleansing foam without irritation

It might seem a bit cliché since it's such a famous product, but I use this to wash my face. On days when I don't wear makeup, this is sufficient. I was worried that the cleansing power might be poor because it's mildly acidic, but it actually removes makeup quite well. Also, it lathers up well just by rubbing it with my hands, so I can finish washing my face with a small amount. Since it's mildly acidic, unlike typical cleansing foams that leave your skin feeling squeaky clean after washing, this one makes my skin feel soft and hydrated. That must mean it's gentle, right? I haven't experienced any stinging after using this.
