Yes, I see the "floppiness" you're referring to. However, I'm curious about how it "distorts your cheek muscles," as you say. Do you mean that it makes the face appear tighter? I presume that the anterior and lateral movements involved here would elongate or 'pull tighter' the zygomaticus muscles due to the geometry here. Is this what you're referring to?
Your cheek muscles go to the outside of your face, what looks really akward, when you are smiling.
