Depressed, Hypopigmented Scars Can Be Improved By Subcision, Fractional Microneedle Therapy, & Fillers
To elevate the scar I would suggest a series of subcision treatments, to which a biostimulatory filler, such as Radiesse, might be added to further promote new, native collagen production and hence greater elevation of scar's base.
To restore a more natural color, i.e. to promote enhanced blending with the surrounding normal skin, I would subsequently consider a series of fractional medical microneedling teatments using a Dermastamp along with tyrosine.
