Normaly the problem is the face shape.
My friend had a baby face (chubby cheeks and a slightly round face I guess) but now she has a gorgous face shape because she has no chubby cheeks.
Unfortunatly, she's got an eating disorder. So I'm going to give you a better way of doing what she did without having a medical problem. Just exersise every day (Expecially face muscels) and do energetic things. You know the jig. If your skinny, still do it anyway. Because it'll lose wait on your face. But don't do what my best friend did, she doesn't eat. So she looks quite anorexic and she's probably hungry all the time so what I'm saying is don't change your eating plans too much, unless you're not skinny of corse.
But if that's not the problem maybe it's your size?
Same thing, exersise. Don't try to lose wait though, just do yoga and exersise every morning. It will help your bones grow. I tried doing this once, didn't last. I couldn't feel my legs the next morning.. I may have took exersising too far. Or I'm just lazy :3
Another thing (works with any issue you have that makes people think you're younger) to make you look older is:-
1) Wear makeup (not too much because you'd look stupid and make sure there are no lines because you'd look even younger then because you'd look like you don't know how to use makeup. So ask your close friend or family if your makeup looks okay before going out in public.
Watch videos on youtube of makeup tutorials to help.
2) Thin Eyebrows. Wax 'em off!! BWAHAHHA! Okay, not all of it obviously. Just make them look thin. Thick or big eyebrows makes people look younger.
But make sure it's done by a profesional, cuz I know this girl who has eyebrows the shape of a triangle and another girl who doesn't have any eyebrows at all because she accidently shaved them off. :/
3) Be mature. Not too mature, cuz you'd be boring. But don't be childish, just do what teenagers do.
WARNING WARNING - AVOID BOUNCY CASTELS.- I know. I'm sorry. Don't cry.
4) I hate to say this but swearing does make people seem older. Don't swear all the time though, like the idiots who swear every sentence (which makes them look like chavs) and don't say it randomly because it'll make it sound forced.
5) Smoke ciggerets.
JOKING JOKING CALM DOWN!!
That makes people look like oompa loompas ;) so don't smoke kids.
I better have an A for my long answer.
OKAYZA BYZA!
