Unfortunately it sounds like your daughters acne is hereditary, as was yours. But all I can tell you is I have been using FaceDoctorRx For three years and it has really helped my acne. I am a 26 year old and still have acne, actually I didn't start getting it bad until I was 18, when I went through some serious stressful events. I think my hormones are also out of whack and I have the worst period cramps, think I have endemetriosis or something. But the only thing I can recommend is what worked for me. i tried Proactiv and lots of other treatments to no avail, maybe you should take her to see a hormone therapist, maybe you can find out if her hormones are out of whack or something. Sorry I can't give any better advice, keep searching someone has to know what you're going through.
