Submental liposuction alone is a targeted procedure that focuses specifically on removing excess fat from beneath the chin, often helping to reduce the appearance of a double chin and enhance the jawline's definition. This procedure is minimally invasive, typically performed under local anesthesia, and involves a shorter recovery time with less swelling and bruising compared to more extensive surgical options. 

When submental liposuction is combined with Renuvion, the benefits are amplified, as this combination addresses both fat removal and skin tightening. Renuvion improves skin elasticity and firmness in the neck. This approach is particularly advantageous for individuals experiencing mild skin laxity, as it not only enhances the jawline's contour but also offers a more youthful appearance with a potentially quicker recovery than a neck lift.

A necklift is a more comprehensive surgical procedure designed to address both excess fat and sagging skin in the neck and submental area. This procedure involves removing excess skin, tightening muscles, and may include liposuction for fat removal, resulting in a more dramatic transformation. The results can be long-lasting and significantly improve neck contour at a cost of a longer recovery time.
