"i have had acne since i was about 12 years old. i am now 50.  i have tried all acne medication out there.  i am now using doxycycline (oral antibiotic) twice a day, clindamycin phosphate in the morning, and trentinoin at night.  for the first time in my life, my face is as smooth as a porcelain.  hope never to stop using this combination of medicines.  no break-outs, peeling or irritation.  please just try and see for yourself."
