I don't know if you'll take this but i hate both. you're still young, try to keep your skin fresh for now. you'll get to wear make up soon enough i swear. id invest in some good moisturisers if i were u. I'm 20 and i still get compliments from guys and girls on my skin when it has nothin on it. looking healthy is still attractive :)
this is just my advice but it's up to u. i only wear them on occasions so I'm sorry if i didn't help much.
I don't use concealer but I like the Dream Matte Mousse for foundation. You don't have to worry about it spilling everywhere and because it is a mousse it doesn't feel greasy or thick when you are putting it on.
