HELP - just got a surgery on my nose, going under anesthesia, and my skin was completely clear when I went in for the surgery and until 4 days post-op I woke up and had a TERRIBLE breakout of little pimples, but some swollen ones all over my face (forehead, chin, cheeks, nose). The pimples are sore too. My skin also became so oily on my forehead. Has anyone ever experienced this? How did you treat it? Based on the pictures, what is my best form of treatment? I was going to try salicylic acid (BHA 2% from Paula's Choice). Any advice is much appreciated!
