If I lowered my dosage do you think everything will go back to normal?

I’m on my second month of Acctane 60mg and the 2nd week in to the dosage I noticed dryness around/inside my vaginal area. I thought it might have been a reaction to my tampon, but I now have rough, peeling, cracked skin on the “lips” and it’s constantly burning, peeling and sometimes bleeding. I went to my gyno and she said to just put aquaphor on it and hope for the best. It’s so uncomfortable/painful to the point it’s hard to wear panties or pants and I resort to wearing maxi dresses.
