Basically, you don't need too much makeup because it's just high school. Focus on grades rather than makeup. Makeup will come when you have a job with extra money to spare whenever; to buy makeup and you can wear makeup.
In my opinion, I think that high school should not be about makeup rather than receiving education. Mainly, because high school students are young and beautiful, should not need makeup. But if you want, you can wear some makeup.
In high school, I wore lip gloss and power (sometimes, to be exact, like 3 times) but mostly eyeliner. Eyeliner like thin lines and colors line black, brown and white. For lip, I wore red lip wear that is not deep. Mostly, any lip wear that is not too deep.
