Does a butt lift makes legs appear longer from the back?

Yes. Lifting the saggy buttocks will also tighten back and lateral thighs which will create an illusion of elongation. Additional shaping with liposuction and/or fat grafts (not necessary buttock augmentation) may further enhance this visual effect. Sculpting lower beck and waist will also contribute to create effect of elongation.You need to consult a very good plastic surgeon to achieve this goal. Good luck.  

If you have a significant buttock dimple and loose skin, an actual butt lift with or without an outer thigh lift will be a good procedure to tighten the butt.  Butt lift surgery however often falters the butt and in order to avoid that, it is best to use your own lower back tissue to also make the buttocks rounder.  A butt lift will probably give you an illusion of longer legs since the bottom of the butt is lifted and sits higher.  However, look at our extensive body lift galleries of almost 50 patients.  All of them have had a butt lift with buttock enhancement.  Best of luck.

Thank you for your question.  Theoretically a lift could make your legs look longer.  From a practical standpoint, the change will be subtle.
