First off, it’s not a fair test to demonstrate skin looseness by exaggerated facial expressions like excessive smiling and pinching the skin over the cheek. When you see the pictures of your face when you are trying to demonstrate your neck, your face looks fine. You have a nice jawline profile, no jowls, no marionette lines. If you want the skin tight during animation of muscles, your face may be too tight at rest. With regard to the pinch test over the jaw, there should be some mobility over the area. The same thing goes for the neck twisting maneuvers. All comparisons should be with your face at rest and in neutral position.One factor involved here is the quality of your skin which is inelastic, it’s thinness, and lack of underlying tissue bulk.Showing pre and post op photos would be a better test of the result.However, in spite of everything I noted, it is possible to have post op relaxation of inelastic skin after a lift and retightening can be considered at least at the six month mark. If you seek a retightening, you should go back to your doctor and express your concerns but will need to wait for any revision until at least 6 months post op.
