hi..Thanks for your query.
I can understand your fatigue with repeated treatments for acne..As we all know ,acne is a very persistent condition and requires real patience with several treatments!
I would say that the treatment was correct for you and you can continue the same.however,there is a need for a detailed endocrinology evaluation in your case.Please do the tests for sex hormone,thyroid
levels as well as 6 monthly Ultrasound
of abdomen to follow up the PCOD.watch out for signs of hirsuitism like extra hair on face/breasts/abdomen etc and hair loss from scalp.
You can start taking Chemical peels
from a qualified Dermatologist
.Salicylic Acid( 20-30 % )peels do help in treating acne and giving a longer remission and also reduces the burden of taking too many oral and potentially side-effect containing therapies.BUT, you should not take take these while on Isotretinoin
