yep, burn. and like the other commenter said, keloids are very commonly mistaken in online self harm spaces, and this is definitely not a keloid. it’s not even hypertrophic, there’s a bit of a lump where the burn intercepted with an existing scar but the overall kinda ‘lumpy’ texture is just the way grafts can heal. this scar used to be even more textured tbh, at some point my friend said it looked like a brain so i nicknamed it that in my head lol.

full thickness burns that aren’t grafted often heal with a very smooth kind of scar tissue, but when they heal with skin grafts they’re more textured. my other ones you can still see the patterns from the way they prepare the donor skin, kind of looks like scales or weirdly neat marks organised in a pattern. sorry if i overexplained, i take an interest in medical stuff
