It's time to crack open your beauty diary. This month, we're getting everyone—from staffers to subscribers—to open up about their personal routines, from the way they experience their Birchboxes each month to the products they just can't quit. Need inspiration? Follow along in a day in the life of our three fearless leaders, products and all. Grab a pen and start taking notes! And make sure to sign up for a Birchbox subscription if you want to join our community.
