As a beauty writer, I’ve had the privilege of being able to try many customized beauty products, from fragrances mixed specifically to my tastes to moisturizers that were formulated to address both my eczema and my skin’s other sensitivities. Though there are a handful of store-bought products that I still swear by, the customized ones always make a deep, lasting impression. My favorite nude lipstick I’ve ever worn—and the only one that has properly emphasized both the yellow and olive undertones in my tan Filipino skin—is the one I custom-made at Bite Beauty’s Lip Lab in L.A. My hair has never looked better than when I formulated a shampoo and conditioner with Function of Beauty to target both the brassiness and dryness of my strands. The fragrance that I can’t stop picking up is the one I concocted with Olfactory. Though customized beauty products are often more expensive than the mass-produced versions, I’m totally comfortable with investing in them because I know they work. Take a look at a few of the best customizable beauty brands below, and get to creating your dream beauty products in just a few clicks. Order anExplorer Boxto try out all nine of the brand’s core scents and pick out your favorite. Then apply the $18 you spent on that box toward a Tinkerer Box to try playing with different added blends so you can suit that core fragrance to your specific tastes. Once you’ve found the core scent and blends that you like, you can order your custom fragrance (with a $20 credit from the Tinkerer Box). It’s highly affordable, but still feels luxurious because you had the opportunity to customize the fragrance to your liking. I’m a huge fragrance snob and I’m totally head-over-heels in love with my Olfactory scent—I haven’t been able to stop wearing it since I got it. To buy: $78; olfactorynyc.com.
