I'd choose the 2nd option for myself.
A lot of people think I am a lot younger than I am because I'm not even 5 feet tall, but they say I act older than I really am and that they can usually tell I'm not a teenager once they get up close and look at my face instead of my body. I hope that doesn't mean I have an "old-looking" face!

What is the mechanism? Just emotions leaving less traces? ("Neurological Botox"?).
That wouldn't apply to me- my facial expressions are pretty noticeable. When I was a kid, one of my grandmother's neighbors actually kept saying I should be an actress because of how disgusted I looked when I talked about math class (and later it turned out that I have a math learning disability.) And unfortunately I am one of those people whose emotions are blatantly obvious, especially if someone I care about says something rude or hurtful I tend to flash "microexpressions" and I can't go back to a neutral expression fast enough for them not to notice.
