It’s impossible to say without seeing you in person, but generally, volume loss in the nasolabial folds can be a big contributing factor to “jowling”. This is best treated by injecting Restylane Lyft into the mid-face and cheek area. This volumizing effect results in a lift in the lower face. However, if you have severe skin laxity, you are probably going to be best served with a surgical facelift. My advice would be for you to schedule an in-person consultation with a Board-Certified Plastic Surgeon in your area to be assessed. Trying to use filler to address extreme sagging in the skin will only result in making you look over-puffed and weird.
