The rear-view photo shows some asymmetry along the lower buttock fold and lower contour, although an in-person exam would be needed to judge the cause. After a second BBL this can come from uneven fat survival, scar tethering, skin laxity, natural pelvic asymmetry, or how the surrounding areas were liposuctioned. Sculptra may soften small shallow depressions, but it usually will not correct a true fold difference, loose skin, or a larger volume/shape mismatch by itself. Depending on the exam, options may include careful fat grafting, targeted liposuction/blending around the lower buttock, release of scar tethering, or occasionally skin-tightening/lifting procedures. It is best to wait until swelling and scar tissue have matured, often 6-12 months, before deciding on a revision plan.
