Thank you for providing detailed information and pictures about your concerns post-thigh liposuction. I'd recommend further upper thigh liposuction to address the crease in your thigh. Specifically targeting the area below the buttock and between the visible horizontal creases, as shown in your third and fourth images, would be beneficial. By doing so, we can reduce the fat in this particular region, thus diminishing the prominence of the crease. As for the sagging in the buttock area you mentioned: 1.) Brazilian Butt Lift (BBL): This involves extracting excess fat from areas like the abdomen, love handles, or lower back and transferring it to the buttock. It not only helps to sculpt unwanted fat areas but also augments your buttock using your natural tissue. 2.) Sculptra Injections: An alternative to surgical interventions, Sculptra stimulates collagen production, offering results that can last up to eight years. The significant advantage is that this procedure is less invasive and can be executed in an office without anesthesia. In conclusion, while the outcomes of surgeries vary by individuals, the above options could potentially help you achieve your desired aesthetic results. Sincerely, Dr. Katzen.
