Since your acne
flares during hormonal
changes the doctor would have prescribed Dianette
.I would better start you on C.Minoz100mg od for 3weeks along with SaslicDS facewash twice daily and topical DerivaCgel by night.This might have a drying effect over the applied area and to prevent this you can use Acnemoist cream by day and use a sunscreen with highSPF since Minocycline
has phototoxic effect and report to me after 3 weeks.
