How can this V shape be fixed 2 years later? (photos)

Hello, thank you for your question. I have utilized several techniques to improve this appearance, but it requires great precision to improve this. You need to find a board certified plastic surgeon who does a lot of revisions. 

Dear nicholevs,
it is hard to tell for sure without an examination. Based on your photos, it looks like you would benefit from a revision surgery. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Hello and thank you for the question. Based on this photo you look like an excellent example for a BBL revision. The optimal BBL outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. These three processes have demonstrated over 95% fat graft take. This means that your results will be stable as long as you maintain your weight. As an official VASER trainer, I am routinely referred unhappy BBL patients and have successfully revised numerous BBLs. A Skype or FaceTime consultation with a BBL specialist can help you get an accurate recommendation and pricing.

If you want us to make an assessment on the outcome of the procedure you need to post before and after pictures so we know what changes were made.Likewise, if you go for any further consultations you should bring it before and after pictures taken by your provider at the time of surgery and during your postop visits.It’s also helpful for any new surgeon to have a copy of the operative report to know how much fat is harvested and grafted. if you don’t have copies of your before and after pictures then  you should ask your provider to forward of the ones they took. It looks like a revision could improve your outcome.follow up with the provider and considering having a Several in person consultations with a new providers  if you don’t feel your current provider can help you with your revision.Best, Mats Hagstrom MD
