My three previous laser hair removal treatments went fine, but I had my fourth one done while in Europe and I think I got burns. I had this done on Tuesday evening and there was some pain and swelling after, and now on Thursday there are burn marks. Will these heal on their own? Are there specific precautions I can take to try and prevent permanent scars? Lasered stomach and armpits without a problem. It’s been 48 hours but I’m worried the area will stay like this.
