<그냥 있을때><턱에 힘줬을때><When I'm just there><When you put pressure on your chin>I'm so stressed out about the muscles under my chin. I look like I have no chin and I want to stop breathing. What should I do? I really put a lot of pressure on my chin because of this all the time. If you have a procedure or surgery, please recommend it. Otherwise, the reviews after the surgery are also good. ..
