My 15 yr old daughter was accidentally sprayed with hot mechanical oil. Where it landed on her legs, she had small red spots and that evening they turned into blisters. Her dad got her BurnJel at the pharmacy. I am more worried about the discoloration as she now has discoloration where the oil landed. The burn places have healed nicely, but we want to know what to do about the discoloration it left behind. This happened approximately 10 days ago.
