Three months after a combined mommy makeover/buttock reduction procedure is still very early in the recovery process, so your results will keep evolving over the first year after surgery. The changes may be even more dramatic (good or bad) if you are losing weight during the recovery process.If there does appear to be a persistent dent or contour irregularity along your hips, that may be corrected with revision surgery - either additional liposuction/liposculpture or fat grafting, or a combination of both.Be sure to check in with your original surgeon and share your concerns about how your results are changing; together you should be able to develop a good plan for addressing any issues that come up as your body continues to heal.Hope this is helpful, and best of luck,Dr. Lim
