Your photos show breast tissue sitting low on the chest with some skin laxity and the nipple/areola position close to the lower part of the breast mound. In that situation, implants alone can add volume, but they do not reliably lift the nipple or tighten loose skin. Placing an implant above the muscle may fill the breast envelope a bit more, but it can also make a low breast sit on top of the implant, creating a heavy or "waterfall" appearance over time. Whether a lift can be avoided depends on your nipple position compared with the breast fold, skin elasticity, breast width, and how large an implant you are willing to accept. If your main goal is fuller breasts with the nipple centered on the new mound, a lift, often with implants, is usually the more predictable option. If avoiding scars is your top priority, an implant-only approach may be possible only if you accept a lower nipple position, a more natural droop, and a higher chance that you may want a lift later. An in-person exam with measurements is the best way to decide between implants alone, augmentation-mastopexy, or a staged plan.
