The current photos show lower-pole fullness and implant settling, but bottoming out cannot be confirmed from photos alone. The key signs are the implant dropping below the original inframammary fold, the nipple appearing too high on the breast mound, or the incision/fold sitting higher than expected on the breast. Comparing your before, early post-op, and current photos with your surgeon is important. At 6 months, most swelling has improved, but implants and tissues can still change. If there is true bottoming out, treatment depends on the cause and severity and may involve pocket repair, internal sutures, mesh support, implant size change, or sometimes a lift if skin laxity is contributing. An in-person exam with your surgeon is the safest way to judge this; earlier review is appropriate with rapid worsening, new pain, redness, drainage, or a sudden shape change.
