Why don’t scars go away?

If you get a cut or scratch that goes deep enough into your skin, your body will form a scar. But why don’t scars themselves heal and go away?

Send it to us at BrainsOn.org/contact, and we’ll help stitch together an answer.  See omnystudio.com/listener for privacy information.
