I have had a mini tummy tuck 2 months ago, my muscles were supp to be tightened all the way as infmd before surgery but my upper ab muscles were not, they are still lax especially when sitting or bending down. my ps attempted to but as my skin was too thin from previous vaser lipo with another surgeon, my ps didn't manage Tighten them. Am now considering an umbilicoplasty to correct my belly button and hopefully repair the upper ab muscles as well. Thanks in advance for any advise.
