I Want to Have a BBL Done but I Have Stretch Marks and Lose Skin Do I Have to Get TT Also? (Photo)

Hello dear!
Thanks for the pictures and provided information as well.
Based on your photos, you are a great candidate for liposuction with a BBL and a tummy tuck, to give you a nice tight tummy and to get rid of the extra skin, and I think you'll get very good results. 
Liposuction allows your plastic surgeon to transform your entire shape. You can improve your waist, back and flanks, and of course your buttock, to give you a beautiful heart shape, along with the tummy tuck.
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 :)

the BBL will not address the loose and hanging skin or the stretch marks on your abdomen. you need a skin excision  for this
