I've had the serious (mostly cystic) acne problems since June 2017. I consulted a dermatologist. I've been on acne treatment since then but it didn't subside. Later on, I was diagnosed with polycystic ovarian syndrome in Oct 2017. Treatment for both is going on and my acne has almost gone. But I still have scarred face which is reducing day by day but not completely. My doctor told me to go for chemical peeling. I have oily face. Please tell me the risks and benefits of it and should I do it?
