I know this is a ridiculous question...

But what on earth is the right amount of a face wash????? Tell me what cleanser you use, and how much of it is the right amount? Can you use a full pump and not irritate your face? Or do you use a tiny finger tip amount, lather it up, and call it good? I know this is basic stuff, but I have no sisters and my mom always just used Cetaphil and a washcloth.
