"i got awful cystic acne freshman year of college. i became convinced that it was hormonal and that besides taking the birth control i was already on there was nothing i could do. i finally went to see a dermatologist and she prescribed me doxycycline and benzaclin. the combination of the two yielded results in just a matter of weeks. i stopped taking doxycycline because at one point it got stuck in my throat and i got tonsillitis. it&#039;s only been half a year and my skin is completely clear! my scars are pretty much gone and my skin is even toned and smooth, finally! i highly recommend it. its drying but it works wonders."
