Acne, the popular, pustules and nodules can be treated with systemic and topical agents and the incidence of sequalae like pigmentation and scars can be considerably reduced. But many time patients turn up for treatment only after the sequalae have set in. Of these scars are the most difficult to treat. Scars can be treated only with modalities which induce collagen remodeling. Let's take a look at how each of the different modalities of treatment works on the scars.
Fillers
Fillers consist of hyaluronic acid in various grades of cross linking. Hyaluronic acid happens to be an intrinsic component of skin collagen. As such fillers don't have a great role in scar correction. But some patients have atrophic scars and depressed scars which need to be filled up. It is here fillers come to aide. Filling is done usually after laser, or microneedling sittings to reorganize the scar or after subcision to cut the atrophic scar bands to promote better penetration and even filling. The most efficacious method to treat atrophic scars are with dermal fillers. Depending on the level of scar, the level at which injection need to be given also varies.Â
