@thomasalterman you are right. I don't why you got downvoted. In UW QID# 17853 it's the same exact scenario. And this is what they said "the morphologic changes in burns occur due to both direct tissue damage and inflammatory mediators released from epidermal and immune cells. Release of histamine and other preformed vasoactive mediators from MAST CELLS in the minutes following a burn leads to dilation of superficial skin capillaries."
