"i&#039;m using  doxy, epiduo and differine for 3 months and it has really worked like my skin became brighter and acne has gone except some pimples i  randomly get. after the 3 months i stopped and i didn&#039;t visit my derm again. i wouldn&#039;t say that my face has back to the first situation but i started to get some red pimples . now i m taking doxy again and m satisfied ! i highly recommend for everyone who suffers from acne"
