2. Only Wear What You Need

More makeup won’t make you look mature. In fact, if you’re in your teens or early 20s, piling on what you don’t need in the way of foundation, concealer and powder can make you look like you’re trying too hard to look grown up. Many times, you don’t need full foundation coverage if you’re young. If you’re blessed with good skin, let it show through. Your prospective employer won’t be thinking how young you look; they’ll be admiring your beautiful skin.
