This patient sought breast augmentation to achieve a fuller, natural-looking B cup. She started with an A cup and expressed a desire for subtle enhancement that would fit her frame. Because of her slim build and concerns about implant visibility, careful planning was essential. The approach centered on providing volume while prioritizing a result that would look and feel in harmony with her body. For this case of breast augmentation, Dr. Jay Xue, MD, selected round, smooth-wall silicone implants filled with cohesive gel. The implants were placed under the muscle using an inframammary incision to create a gentle sweep on the chest while minimizing risk of implant edges showing beneath the skin. This technique was chosen specifically for her thin tissue, allowing for both a natural appearance and implant support. Her results show a balanced, natural contour with soft volume. The transition from A to B cup meets her goals, and the implants blend effectively with her anatomy. The patient was involved in decision making throughout the process, emphasizing size and implant type preferences in collaboration with Dr. Xue.
