Scars can resurfaced with lasers or surgically...first we need to see what type of scars it is? Wether its elevated (hypertrophic)or deppressed (atrophic). Onething i remind you, scar is always a scar..only we can improve the visibilty & resurface it ,as much as possible.
Next Steps
kindly send the photos of the scars...so that i can tell you clearly what should be done to improve the scars.
