I'm not sure what you mean...are you trying to use Dan's AHA cream as a face wash? Because I don't think that would work because it's not a cleanser, and it's a cream, you can't wash it off like with a cleanser? Also, I'm curious as to why you want to stop using the cleanser to begin with?
I would advise against it...unless you mean you're trying to substitute the cleanser with a different cleanser that has AHA in it??
