Be warned: Sephora thinks it is okay for someone else to shop using your account as long as your names and birthdays are "similar." Are you okay with that? Please contact Sephora and tell them it's not okay and you are not going to stand for it.
If you have loose eyeshadow pigments that you're obsessed with and want to wear it as a lip shade, blend it with a little bit of a salve, like VMV Hypoallergenics Boo-Boo Balm, or petroleum jelly in a spoon and swipe it onto your lips. Voilà!
