Why don't scars disappear as skin is shed?
Over time, scars from accidents and injuries can fade, but why doesn't the skin return to its original state?

Scars form at any injury site that takes more than three or four weeks to heal. The body produces collagen fibres in a criss-cross pattern. The normal shedding process of skin doesn’t affect scars because it only involves the migration of the epithelial cells from the base of the epithelium to the surface. The scar is a separate scaffold of collagen fibres and the epithelial cells just travel around it.
