Muah!💋 It’s National Lipstick Day! From Fenty to Rare Beauty to good old-fashioned Vaseline, none of our Sephora Favorites would exist without scientists working on them in the lab.

Let’s take a look at the cosmetic science behind some of our fave products.

Meet Roselin Rosario-Meléndez, an inventor/polymer cosmetic chemist. Roselin works with extreme wear makeup and holds 37 patent applications worldwide. She is most notably known for her work creating Maybelline’s SuperStay Matte Ink, an extreme wear lipstick. Roselin is an If/Then ambassador, and she was also a part of our #GirlsWhoCode “Make That Change” campaign.

Have you ever wondered how lipstick is actually made? Here’s a first-hand glimpse at the science behind Glossier’s lipstick.

Did you know you can 3D print makeup? Grace Choi’s love of beauty and STEM inspired her to invent the world’s first 3D makeup printer. She currently works at Tiktok and uses STEM to create some of our favorite beauty-inspired filters.

Kristen Wells-Lewis created Black to the Lab, a fun, educational kit that teaches young Black girls about STEM’s impact on the cosmetics industry. She aims to use the science of beauty to open up young girls’ minds to STEM-related career paths.

We want to hear from you! Are you team lipstick, lip oil, or more of a gloss girl? We want your beauty recommendations! 👀 Whether it’s tooth gems or you just stick with chapstick, let us know your fave lip product in our comments.
