Will impetigo leave scars?

Temporary changes: Impetigo usually affects the upper outer layer of skin, so there should not be noticeable scars after the color changes even out over a year or so. If the patient scratched at the scabs during healing, and made deeper wounds, then permanent mild scars can occur (just like in chicken pox, where scars normally don't occur unless the scabs are scratched off by the patient).

Maybe: If the condition is prolonged or if there are repeated infections it may leave scars. Also keep the red areas out of the sun till the red color returns to normal.
