Thank you for your question. It is possible to undergo breast augmentation without a breast lift, but the results will depend on your individual anatomy and desired outcome. From the pictures you have provided, it appears that a breast augmentation alone may be able to achieve a natural-looking result by adding volume to the breasts. However, it's important to keep in mind that a breast augmentation will not correct any sagging or droopiness in the breasts, and will only increase their size. If you desire a lifted appearance, a breast lift may be necessary in addition to breast augmentation. It's also important to consider the long-term effects of breast augmentation alone. Over time, the weight of the implants can cause additional sagging and droopiness in the breasts. If you are concerned about this, a breast lift may be the best option to achieve long-lasting results. Ultimately, the decision to undergo a breast lift in addition to breast augmentation will depend on your individual anatomy and aesthetic goals. I would recommend scheduling a consultation with a board-certified cosmetic surgeon who can evaluate your anatomy and discuss your options for achieving your desired outcome.
