Weight Loss Post Chin Lipo?

It is very important to post a full set of facial and neck photographs from all angles to make a determination about how best to proceed with the appropriate neck procedure. Probably best to post those pictures after your 20 to 40 pound weight loss. At 37 years old, your skin tone should be just fine. It's also important to understand that here are two compartments of fat in the neck, they're located both above and below the platysma muscle. Liposuction can only accomplish removal of the fat deposits above the muscle, while a surgical neck lift with a platysma– plasty is required to remove the fat compartment below the muscle.

For most people weight loss is a gradual process. I suggest taking pictures and comparing if you’re concerned about facial aesthetic impact of the weight loss.
Most people look and feel better being at an ideal weight.
