acne
"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."
