Filler for Indentation from Scar Injection?

It's fairly common to end up with a slight indentation in an area of scar that was treated with steroids.
The remedy is fairly straightforward. These indentations may be significantly improved by an Injectable Filler treatment. I would personally use Silikon-1000 for permanent results. In my experience, Silikon-1000 is excellent for hypotrophic depressed scar tissue in the lower extremities; especially small scars from liposuction cannulae.
I hope you find this helpful.

Kenalog is commonly injected into hypertrophic or keloid scars to flatten and soften them. If the injection is too deep and/or the keloid concentration to high the skin can be thinned and the underlying fat cells can be killed. This is seen from the outside as an indent. The only treatment available is to liposuction a small amount of fat from elsewhere on the body and inject it into the indent.

You probably received kenelog for scar resolution. Kenolog can unfortunately melt fat too since it is a steroid. The best way to treat the indentation is fat transfer in my opinion now. Fat can be grafted under the indentation to correct for this. More than one attempt may be needed.
