I've tried everything with a derm. TODAY I went in for a CHEMICAL PEEL glycol peel 30%. The esthetician suggested I do at least 2 IPL treatments since I mentioned my cystic acne around my chin and jawline were a huge concern for me. She said after 2 treatments patients see acne gone. Any Neg side effects? What type of machine should I be looking for? I heard not all are machines are created equal, Also, what should I truly expect?
