Tummy liposuction is ideal for people of a healthy weight who suffer from localised fat deposits but have good skin elasticity. Liposuction tummy removes fat under your skin, with (virtually) invisible scars and a shorter recovery time. If the elasticity of your skin is no longer as good, liposuction abdomen has the disadvantage of leaving the skin on your lower abdomen flabby. Especially when you get a bit older, this can be a drawback.
A mini tummy tuck, on the other hand, is suitable for people with excess, sagging or wrinkled skin in the lower part of the abdomen, often after weight loss, pregnancy or due to ageing. This procedure offers both fat removal and skin tightening for a tighter abdominal profile. You should expect a larger scar, which the plastic surgeon will hide as much as possible in a skin fold.
In short, both techniques have their own advantages and disadvantages, and may or may not be suitable for your body. This will be revealed during a no-obligation consultation.
