"i was prescribed doxycycline the summer. i had moderate to severe acne and within a month my face had almost cleared all up. it was great. i continued taking the pill for a year and a half but as i continued i realized my acne was slowly coming back even with the pill. my face had become resistant to doxycycline so i now switched to another antibiotic. my only advice to you, try it if you want to but as many others have said it&#039;s only a temporary solution."
