Walking into Sephora with a zero makeup aptitude can be really intimidating. There seems to be endless knowledge and methods you need to understand, right? Wrong. Rules are meant to be broken. While there are thousands of books out there with how to-guides and rules on what you absolutely shouldn’t do with makeup, there is no Supreme Court of Beauty that will punish you if you bend the rules a little. And, those rules change all the time, in tandem with the latest innovations and beauty ideals. So, when and if you pick up a beauty book, take the advice with a grain of salt: Times change, and your beauty rules should change, too.
