Are injectable fillers effective in treating scars?

Question: Are injectable fillers effective in treating scars?

Answer: There are a few isolated circumstances in which I do like fillers, either fat or fillers off the shelf.  This is when the scar is atrophic, meaning that there is a depression to the scar.  This can sometimes make the scar more obvious because of shadows that are caused by the depression.  In this case, a filler just under the surface of the skin can be even more effective than surgery.
