A month ago I accidentally put my hair on fire. It has happened many times before but this time the flame burned my face too. Because I didn't feel any pain at all, I didn't wash my face with cold water or put on some special gel or something. But the next day there was an awful wound on my cheek! It was about 2x2cm big and it looked soooo terrible! After two weeks the wound healed but now there's this reddish spot that I want to get rid of. How long will it heal? Or will it heal at all? What products should I try?
