In terms of my own lash and brow growth goals, I’d have to say that I’m given a head start by my genetics: my brows are naturally thick and thick, but there are a few sparse areas after over-plucking as a teenager that I usually pencil in with strategic application. My lashes (naturally long and black) are also naturally blooming so I want to keep them that way; The Augustinus Bader Serum is perfect for both my brow and lash goals. At $150, Serum for eyebrows and eyelashes is at the highest level of comparable products. But if you want something as close as possible to a prescription lash enhancer like Latisse, I’d say this is it. (By the way, Latisse is not recommended for use on the browbones or lower lash line and can potentially darken your eye color if used incorrectly.) During a recent press call, the famed esthetician (and cancer survivor) shared his personal journey with the product—and, frankly, , the results were incredible. The brand kindly sent me a tube to test, and after a week of consistent use, I’m hoping it will keep my brows and lashes shiny for years to come.
