How can I fix these BBL dents and dimples on both cheeks of my butt?

Hello, thank you for your question. It appear that you may benefit from a revision, I recommend you to schedule a consultation with a bard certified plastic surgeon.

Thank you for your question and pictures.   it is very difficult to give you and accurate response without seeing the full 360 picture.   first I would recommend you do nothing till at least one year after your last BBL.  Second yes there is other procedures to fix contour asymmetries.   And finally you need to find a Board Certified Plastic Surgeon that specializes in Re-Do work. 

Dear IKinTexas,
I understand your concern. However, without a proper assessment it would be difficult to determine what is wrong. If you are not satisfied, you can get additional fat transfer or Sculptra. It is best that you visit your plastic surgeon for further assessment. Only after thorough examination you can get proper recommendations and advice.

These complications can be resolved using high defintion VASER liposuction. The definitive correction for liposuction deformities requires the advanced technology of ultrasound assisted VASER liposuction. As an official trainer of VASER liposuction, I encounter suboptimal liposuction outcome referrals weekly. VASER liposuction has been the only modality that has consistently corrected liposuction caused deformities. VASER liposuction ensures a smooth contour regardless of severity of contour irregularities by virtue of being able to remove any and all remaining fat comprehensively and uniformly. Finally, when skin redundancy irregularities are observed, Renuvion technology can be simultaneously applied to tighten your skin to optimize your overall contour outcome. A Skype or FaceTime consultation with a VASER specialist will help you get an accurate recommendation and pricing.
