Okay, let's see if I have this straight-
So what she's saying is that in order for repeated movement to create a line, your skin has to be pretty old/not as strong as it used to be. So, if you beef up the muscles in your face, it makes it stronger underneath to hold up the skin and prevent it from wrinkling just from movement, or otherwise. It rejuvenates your skin from the inside out, basically. It's different from a face lift, because you're firming it up instead of making it taut.
Does that make sense?
It makes a lot of sense to me! That sounds awesome. How exactly do you accomplish that though? exercises?
