"on my second week of doxycycline and i already see major improvements. i mostly break out on my jaw area and so far i haven&#039;t gotten new breakouts besides maybe one or two pimples whiteheads that go away very quickly.  it has got rid of my cysts, hard bump acne. i mostly have scar and hyper pigmentation now. didn&#039;t vote 10 stars because i haven&#039;t finished first month yet"
