What procedure will give me smooth legs and a nice butt? (Photo)

From what you’ve described, there may be signs of lipedema, but it's very difficult to diagnose without an in-person medical evaluation. A consultation with a board-certified plastic surgeon or vascular specialist would be the best next step. They can assess whether it's lipedema or simply stubborn fat distribution and skin texture caused by genetics, hormones, or past weight fluctuations.
For smoother legs and better shape, there are both non-invasive and surgical options. Some possibilities include:
Liposuction (especially HD lipo or power-assisted lipo): to contour the thighs, stomach, and enhance your waist-to-hip ratio.Fat transfer to the buttocks (BBL): for more volume and projection.Skin tightening or cellulite-reducing treatments (non-surgical options like Morpheus8, BodyTite, or Cellfina).
It’s great that you’ve already made amazing progress with your weight. At 165 lbs and 5'4", you're in a range where body contouring can make a noticeable and beautiful difference, especially if you’re close to your personal goal weight.
Here’s a great transformation from a patient with a similar concern

Hello, thank you for your questions and photos! Unfortinitaly liposuction will not help with the dimpling appearance on your legs and butt area. That is a structural problem from cellulite. Liposuction will help improve with fat reduction to the legs, but it could also make the dimpling worse when you remove the fullness. If you have loose sagging skin in the middle of your thighs you may be a candidate for a medial thigh lift. If surgery is not something you want to do, then Venus Legacy could possibly help smooth out the dimpling on your thighs and butt. This is a weekly commitment for 8-10 weeks and a treatment you will need to keep up with on a yearly basis to help maintain the results. It is not a once and done treatment. Best of Luck!
