Scar treatment belongs to reconstruction and repair. Relatively speaking, plastic surgery institutions are better at it. The specific repair method depends on the shape of your scar. Like the original scar with shallow surface and regular shape, it is necessary to consider whether there is a need for treatment.

If scar hyperplasia or atrophy is obvious, it is necessary to consider surgical resection of hypertrophic scar, or to separate subcutaneous tissue and pull the edge of the wound to make up for the depression. Of course, there are other scar repair methods, because I can't see your situation, so it's hard to make a specific judgment. If you don't know, you can ask me.
