Hi thanks for your question.
You’re suffering from recurrent folliculitis
with occasional abscess formation.
You have taken a course of isotretinoin
for 6 months.
This drug is used to treat sever forms of acne.
Get your blood glucose
done and try different antibiotic like doxycycline which will also take care of acne as well as of super added infection.
The process, of complicated acne
usually get settled with age.
Hope I answered your question
