I know plastic surgeons have been trying out "thread lifts" for facial rejuvenation procedures to lift areas of the face and neck. Actually, I was one of the first doctors utilizing this technique; however; the results did not last and were not very significant. The most popular forms of Butt Lift are a Brazilian Butt Lift- which utilizes fat transferred to the buttocks to add volume and lift the buttocks. The other method is through a lower body lift where an actual incision is made above your buttocks (like a tummy tuck on your back), excess skin is excised, and the result is a lifted rear-end with a tighter appearance to the skin, but it does not add volume. I do not think a thread can create a lifted and shapely buttocks. If you already have tissue to work with and just want to lift it a little, I think the weight of the tissue will be too great for a thread to hold. If you are lacking volume, a thread will do absolutely nothing. I suggest you research a Brazilian Butt Lift. Besides lifting and enhancing the shape of your butt, the surgeon utilizes liposuction in order to harvest the fat to be transferred so you get the added benefit of sculpting other areas of your body. Good luck.
