Liposuction is recommended for clients who are between 18 and 78 years old. However, the surgeon also considers the overall body and health profile of a patient who wishes to undergo liposuction. Keep in mind that the elasticity of the skin decreases with age. Therefore, it may not be ideal to remove a lot of fat in older patients because their skin may not be able to recuperate with the loss of underlying fat, making the treated area sag.
