People are always asking former Marie Claire beauty director Jennifer G. Sullivan their beauty questions, which makes sense because (a) she has learned a few things in her years as a beauty journalist and host of Fat Mascara, a podcast that takes a closer look at beauty culture, and (b) the internet is a soup of conflicting advice and Google ads that feeds our worst insecurities without providing much assistance. If there are two things Jenn loves, they’re calling out b.s. and helping people feel better about themselves. So that’s what this biweekly column is for. No concern is too vain, trivial, obscure, or embarrassing — she’s here to help. Send your questions to AskABeautyEditor@nymag.com.
