Fit and active but lower body is untoned. Will gaining weight and muscle fix this, or do I need surgery? (photos)

Buttock “sagging” is usually a combination of loss of volume or deflation (after weight loss or post-BBL) and/or the effect of genetics, 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.

Hello !

You could greatly benefit from EMSculpt (with a minimum of 4 sessions) and CIT Macroneedling (which stands for collagen induction therapy) which can also require a few sessions - but you can already see improvement after the first one.

I hope this helps, best of luck !

Your body has a fairly normal appearance of a slim young male in moderate physical shape.
I see no indication for needing surgery. I do not recommend gaining weight. Continue exercising and accept the genetics you were given.
