I hate having a baby face :C, do you think make up will make me look my age?

I guess so , but there are disadvantages too

Everything in life is a trade off. Right now you are probably being treated like a child, which is one of the biggest insults you can make to a young adult. On the other hand, in a few years, looking younger will gain you advantages in relationship and employment. This advantage will follow you the rest of your life.
You will really appreciate it when you are in your fifties and sixties facing age and sex discrimination. Older women have had a harder time finding jobs than older men and younger women for decades.
It may not feel like it now, but it is a blessing.

You're right, i never thoughtabout the job & discrimination thing you, i suppose i can try deal with not being treated seriously, thank you :)

Im no expert with makeup, but i think it makes most girls look older..?
