The results of the procedure will last for many years but are not fully permanent. This is because the body continues to change shape as we age, and skin elasticity continues to deteriorate. The results will be meaningful and last a number of years, but will not be completely permanent.
We do not recommend having a mummy makeover if you plan to get pregnant again, as this will materially impact any results achieved. We also recommend that any significant weight loss occurs before surgery and not afterwards.
This is because excessive weight loss can negatively impact your results by leaving excess, inelastic skin in treated areas.
