How can I tighten skin on my neck?
I'm 44. When I swallow/stretch my neck, I have vertical wrinkles in the center of my neck. I also have a more prominent muscle on the right than the left. If I clench my teeth, the edge of a muscle sticks out in the center of my neck on the left side only. If I tilt my head to the left, the skin is lax and crepey. This doesn't happen on the right because of the large muscle see pic). How can I tighten the skin?
