Chin liposuction tends to have impressive and consistent results. You may see some results right after the surgery, but expect it to take a few months for your new jawline to emerge.
There could be a sagging of skin after the surgery in few, which mean that your skin has a low elasticity, or isn’t healing effectively.
In such case, you may want to talk to your surgeon about a follow-up surgery, such as a face lift, neck lift etc.
