So I have this weird thing happening all over my torso, and rarily on the soft skin of my arms and mid thighs.

So basically these little pink blotches keep showing up on my skin. They dont itch, theyre not sexually transmitted (As its been going on since before I was sexually active) and basically if feels like a peeling temporary scar. They usually dont stay long and they dont hurt it litterally just feels like scar tissue that peels a bit. Does anyone have an idea what this might be? Its been going on for years. ;-;
