Will I Have Saggy Skin After Lipo (For Bbl)? (photo)

Hello dear!
Thanks for the question and provided information as well.
Based on your pictures, you are a great candidate for liposuction with BBL, and I think you'll get very good results. 
Liposuction allows your plastic surgeon to transform your entire shape. You can improve your abdomen, thighs, hips, back and flanks, and of course your buttock, to give you a nice heart shape.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

You don't have to take fat from your stomach if you don't want to, but this area usually offers a sufficient amount to achieve a good contouring of the buttocks. There might not be enough in your back and flanks. But you're right, this will most likely leave skin saggy on your stomach if you only get liposuction.
