After? I know that she does it in the shower, would after make a difference?
My suggestion was that perhaps she was aggravating it too much, ... or that maybe she should try alternative medicines or therapies. Rather like when you have spots in certain places on your face and where they are is an indicator of the cause (hormones, pollution, stress, some sort of deficiency), maybe these are a similar telling sign.
I know that they really bother her, and that she is very self-concious of them...!
