Hello Doctor, I graduated MBBS, Im suffering severe acne since 7 years, I used deriva, clincin ointments for 2 years. Took chemical peels 8 months before. After chemical peeling skin was neat and clean, but acne is back again with pus. they are almost nodulocystic. Im using Tretenoin 0.025% since 8 months, and Retino AC occasionally. Acne are leaving scars and spots on face. What should I do now to get rid off those acne, scars and spots ? My ultrascan report was normal, no PCOD. Kindly suggest a permanent solution Doctor.
