I was stupid thinking this salt and ice chalenge would not hurt me but I ended up with a big purple mark that burns can someone tell me if it will go away my mom knows and I told her I would not do it again but I'm pretty mad about this so someone please answer my question.

It will take a very long time to stop being purple and you may or may not have a scar. You basically froze your skin, not burned it, even though it feels like burning. It's like frostbite. That's how salt + ice make ice cream freeze.

I had a motorcycle exhaust pipe burn scar for many years before it fully disappeared. But my skin is a type that scars don't disappear from easily. I still have stitch marks from 50 years ago.

I think so cause I did it like a hour or 2 ago then I did it again to the same amr but a different spot I guess go to the hospitital if you feel like its getting worst actully it could cost cancer I read but nothing happen to me yet only I go burns and a lump
