Great Question! But it really depends on you and what you are comfortable with and the look you are after. For many years I only wore a lip gloss and a blush. Thanks to having presentable skin, I did not need much. Then came eyeliner & mascara. I did not discover or need foundation till 15 years later.
But before make you should invest in PROTECTION!!!! I wish someone would have told me that when I was 15! sunblock & moisturize or one product that does both, then your makeup!!!
