"i have suffered from acne for 10 years (currently 25). i have cystic type acne, lots of blackheads and oily skin. i have been to multiple dermatologists throughout the years and tried countless products, both otc and prescription. i have had amazing results with my current regimen which includes doxycycline, aczone topical gel applied at night and panoxyl face wash (otc). the doxycycline made a difference right away! i still got maybe 1 cystic type zit a month for the first 3 months and now basically not at all. the aczone and panoxyl help combat the blackheads and tiny zits the antibiotics doesn&#039;t. the biggest downfall is the nausea. i highly recommended this for those with cystic acne and be sure to take after meals. i am happy to finally be acne free!"
