Dear Zenobia, If by cellulite you mean skin irregularities due to skin laxity or irregularities from all kind of injection including fat injection, than, butt implants definitely can improve and smooth the skin of the butt. The implants tightens the skin and smooth it . I have done it on quite a few patients with spectacular improvement. You can contact my office and obtain the before and after pictures , which will convince you in that regard. That improvement occurs, for sure, with my technique, which is the sub fascia technique (on top of the muscle). Doctors who use the sub muscular or intra muscular technique might not achieve it. Always, consult with experienced board certified plastic surgeons , who use the sub fascia technique, in accredited surgery center for your safety. Most importantly, check the before and after picture in the photo gallery to make sure that they are numerous, consistent and attractive with nice 'S' curve, nice projection, round hips (hour glass) , nice skin and natural look. Best of luck, Dr Widder
