So far, there is very little evidence that laser liposuction (or any other liposuction for that matter) tightens the skin. Only one study on the abdomen showed a small change in the skin that could be interpreted as tightening. However, the marketing of the laser liposuction companies is geared to suggest that the skin is tightened. The same claims were made when ultrasound liposuction became available in the late 1990's but over time, no one could show that ultrasound liposuction was any better than regular liposuction in tightening the skin. My suggestion is save your money on laser liposuction until we have independent evidence that it results in clinically significant improvement and is superior to regular liposuction.
