4 weeks post-op there is a large indent. Will I need a revision? (photos)

Hello dear!!
Thanks for the question and provided information as well.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation and irregularities are normal.
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)

It is hard for us to give advice without knowing what your butt looked like pre-op. What I will say is that things tend to smooth out and settle in over the first 6 months after surgery and things will look different. I can't say whether the indentation will smooth out completely but it will improve from what it looks like right now. 

Dear missteaghanmartinez,
I understand your concern and it is quite normal to be concerned about the outcome following a BBL surgery. However, you are still in the very early stages of the healing process.Your will need to be patient at this moment and follow what your surgeon has instructed you to do post operatively.At the early stage of the healing process, the tissues are still swollen. Once the swelling subsides  you will be able to see the final result of your surgery.
