this may sound crazy..but it's really simple.
tell her to try for one wk..and see if it works.
run warm water in sink....or just let run. don't use a wash cloth...only use your fingertips to scrub your face with just plane water...no chemicals....WATER ONLY!
you can feel your dirt in your pours with your fingertips, they are like a brillo pad built in...Let me know...really. to many things out there that just feed your pours..just use water and fingertips...tks..it works for me
