Allow me to try to answer this question without any photos. Please keep in mind that in person consultation with physical exam, or at least a virtual consultation, is necessary before providing any legitimate recommendations. Buttock “sagging” is usually a combination of loss of volume or deflation and/or the effect of aging and gravity. So, I personally first treat patients like you by restoring volume to the buttock with a buttock implant. This will create a more desirable smooth and rounded perky buttock profile. If not adding volume with an implant, the buttock will be shortened but may appear more flat with just a buttock lift. A lower buttock tuck is usually then performed at six months following implants. In this sequence, the implants have fully settled into final position so that any remaining loose skin can be most accurately identified and removed with the lower buttock tuck. Please note, because an extremely few number of board certified plastic surgeons specialize in buttock implants, you may have to travel away from your local area to seek consultation with this particular type of surgeon. Glad to help.
