Can I fix fat that was transferred too low on my buttocks?

Hello and great question. I appreciate the time you are spending researching this procedure. My name is Dr. Matthew J. Nykiel. I am a Board Certified Plastic Surgeon, a Fellowship Trained Cosmetic Surgeon, and a Butt Augmentation Specialist.
Based on your photos, you are a candidate for a Liposuction/ Fat Transfer revision for improvement. l recommend you to make an appointment with a board certified plastic surgeon to talk about your desired outcome. I hope that helps! Best of luck!

Hello, thank you for your question. It is difficult to tell what the lump might be.  I would have to examine you to determine if there was a problem with healing.  

Hello, thank you for the question and provided information as well.. after analysing your case.. I can say you're a good candidate for a BBL revision, this would fix your problem, give you great results and improve the look of your butt.
It is important that you communicate to your board-certified plastic surgeon what are expecting, to make certain that your goals are realistic. It's helpful to show pictures of results you'd like, but please keep in mind that these are other people and your body is different from everybody.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Best of lucks.
Dr. Luis Mejia
