"this is my 3rd month on doxycycline and my face have shown great improvements! i&#039;m 19 with oily skin and before i had moderately severe acne with cysts, papules and pustules.  at one point it hurt and annoyed me so much plus lowered my self esteem that i decided to meet a dermatologist . she prescribed 100mg of doxycycline along with 5% benzoyl peroxide to be taken daily . during the first month, it was horrible. my face broke out terribly but i guess that was a part of it, clearing out the disgusting stuff inside our face . in the second month my skin start to clear up, and now i can say that i&#039;m 95% acne free with occasional small zits during period but nothing hurt as much as before. the point is, don&#039;t give up :)"
