I have three small scars on my wrist from burns. I burned my arm on the grill about ten months ago, and, because I was SIing I didn't put cold water on or anything. The scars are now pale lilac colour, and the skin is a bit dented like its hollow underneath. Will they heal completely? I'm thinking of having a tattoo over them, but will the ink bleed because of the scar tissue? Any advice gratefully received xx
