I think it can, think about the faces you make when you're happy, mad, and sad.
My mom always told me not to frown so much because I'd grow into an old man lol.
It changes your face when you're on it doesn't it? Makes you look young and rejuvenated.
That's because you got happiness literally rushing out of your brain into your body.
Abuse it, and you got less of it in your brain, you might end up looking like you're not getting enough rest or upset. Especially if you crash pretty hard after every session.
I doubt long-term effects on the face are serious though, as long as you give your body good rest between sessions.
