Innisfree Volcanic Clay Pore BHA Cleansing Foam

My skin tends to be sensitive, so I have used various types of cleansing products. Among them, I have been using the Innisfree Volcanic Pore BHA Cleansing Foam without any breakouts. It is not expensive and suits my skin well, which makes it even better. I used to get breakouts when using oil-based cleansers, but I don't know why it only happens with oil-based products.
