I used doxycycline +
vitamin C + ZNSO4 for 40 days. I got much relief, so discontinued doxycycline and stay with only vitamin C and Clindamycin and nicotinamide gel for 20 days. But now I found some forehead acne, so can I start Minocycline with vitamin C and (Clindamycin and nicotinamide gel)? In brief, can I use oral Minocycline?
