I recommend Ponds Cleansing Foam.

This is the Ponds cleansing foam that many people use, and I highly recommend it. I bought it at Olive Young, and they seem to have promotions on it quite often.

You probably use a mildly acidic cleansing foam, but this is a mildly alkaline one! I heard that you should use a mildly alkaline foam for acidic sebum.

I love that a small amount of foam lathers up well and leaves my skin squeaky clean after washing! Above all, I am very satisfied because the price is quite affordable compared to the quantity.
