After any liposuction procedure the volume of the fat layer under the skin is reduced – sometimes dramatically. Regardless of the amount removed, there is always a question about how well the skin will retract and redrape over the treated area. Thicker, more elastic skin typically retracts better than thinner older skin. Factors that affect the skin’s elasticity include the patient’s age, gender, and skin pigmentation type.
From an aesthetic perspective, there is always a trade-off between the amount of body-contour remodeling that can be achieved through the removal of subdermal fat and the post-surgical appearance of the skin as it conforms to its new shape. Poor skin retraction will result in wrinkles or folds. Post surgical appearance will also be affected by pre-existing skin issues such as laxity, atrophy, and stretch marks.
As an example, the following photos shows good skin retraction after Vaser liposuction, however, pre-existing stretch marks can still be seen in both the before and after photos.
