My regular followers know only too well that I am no fan of the use of permanent fillers, as permanent fillers can translate into permanent complications, not just immediately after injection, but five, ten or even tweny+ years later.. And these complications can be very difficult to treat. And not uncommonly these late complications can first be triggered by some kind of manipulation of the area, such as during dental procedures or if other safer HA fillers are later used in the same area. So, please keep this in mind when doing your search for treatment of this scar, since Bellafil was used in that area. In general, subcision is a very safe and effective and relatively inexpensive technique for elevating and smoothing all kinds of atrophic (depressed) scars from all causes in all skin typies. I have been performing this procedure since 1995 with very gratifying results. You would be wise to seek out an experienced, board certified cosmetic dermatologist and be sure to tell him/her that you have been treated in that area with Bellafil. Hope this helps.
