The photos show upper pole emptiness, but they also suggest mild to moderate breast ptosis or pseudoptosis rather than just loss of fullness. A true grade depends on where the nipple sits compared with the inframammary fold on an exam; from the photos, the nipple position looks close to that fold and the lower breast has some descent, so I would not call it significant ptosis. If your goal is only a little more upper fullness, an implant can help, but it will not reliably lift a low nipple or tighten a loose skin envelope. If you want the nipple higher and the breast shape tighter, a lift, with or without an implant depending on your desired size, may be the more predictable option. An in-person measurement is the best way to decide between implant alone, lift alone, or lift with implant.
