"i use to have really bad cystic acne on my forehead,  between my eyes and on my jawline. i started using this medication my senior year in high school along side accutane and my problems were solved.  my prayers answered.  i quit using it after high school and i began to break out again.  just last year i began taking it again,  just the doxycycline and i feel happy with the results.  my acne is not totally cleared up.  but i rarely, almost never get cystic acne. just a few little ones here and there. i find that benzoyl peroxide acne wash is best pared with this medication for me.  but everyone is different."
