"i used tetracycline hydrochloride ointment together with betamethasone valerate for the terrible breakout i experienced last year (based on doctor&#039;s prescription). i must say that the combination worked well for my acne except that my face became very fair, almost white ( i am black by the way) and the acne scars became very conspicuous. i was advised to stop the treatment by my doctor. my face returned back to normal after a while and the scar disappeared almost completely. unfortunately the breakout is back and i am planning to go back to this treatment as every other regime isn&#039;t giving the desired result."
