My main question is: why is my skin sagging so significantly and rapidly, even after undergoing a skin and muscle lift?

Dear Ivonnedutch,
I understand your concern. However, without a proper assessment, it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment or ask for a second opinion. Only after a thorough examination, you can get proper recommendations and advice.

In the end, surgical outcomes are based on the patient’s candidacy for the procedure and how the procedure was performed.
If the outcome of your last operation didn’t meet your or your surgeons expectations, then neither your expectations for the procedure, your candidacy for the procedure or the procedure itself was insufficient or incorrect.
Having had three previous operations, your situation is too complex to give you a simple explanation of why your results look the way they do.
The one thing that stands out as being an explanation to your problem is that it looks like fat was removed from the upper part of your thigh below the buttocks at some point.
To really understand your outcome we need to start at the very beginning and look at before and after pictures for each of your three procedures.
If you don’t have before and after pictures, then you should ask your providers to forward the pictures they took.
A proper Second opinion, consultation would also involve reviewing operative reports to know exactly what was done during each procedure.
If the primary procedure is not done correctly then the chance of having a long term quality outcome goes down,
Different providers will have quite different opinions on how this procedure should be done.
I think the majority of your problem stems from inappropriate liposuction during one of your previous procedures, removing fat from your thigh, destroying the transition between your buttocks and lower extremity.
Some providers remove fat in this area in an attempt to make the buttocks look large.
Personally, I don’t see the BBL as a gluteal procedure.
It is a procedure that is done to enhance the femaleS-Curve. As providers it’s important to always respect the perfect female curve, and it should not be tampered with, but rather enhanced with every maneuver we do. If providers are willing to destroy the S-curve for the illusion of having a bigger butt then that’s what they do.
Delivering consistent quality, liposuction, and fat transfer results turns out to be more difficult than most people realize.
The number of plastic surgeons who approach mastery of this kind of work is in reality very small.
As mentioned previously, there are also quite different views of what an ideal female body should look like.
To me any outcome that approaches unnatural is in my opinion, not a success.
In ever picture I see the unnatural transition from the lower buttocks to the thigh as the primary problem.
I don’t see any need to lift anything.
The female S-curve should be smooth and continue from the knee to the armpit.
If you look at pictures and draw out the S-Curve you will see where to problem is. Do your curves look like a smooth “S”?
Whenever we assess an area in regards to Aesthetic outcomes, it always needs to be in context with the surrounding areas.
Avoid cropping pictures and always show pictures of the full torso from your neck to just below your knees.
Before prescribing an operation, we need to have a clear understanding of what the problem is.
I think that is why your last procedure did not accomplish what you had hoped for.
I don’t think your surgeon sees the problem.
Perhaps my response is different than how others view your situation. I simply say it like I see it.
Once fat has been Erroneously removed getting equal final outcome becomes almost impossible.
Best,
Mats Hagstrom MD
