When you hear "beauty filters," you probably think of the typical TikTok and Instagram filters that add makeup and sometimes alter your facial features, all in the pursuit of a prescribed beauty standard. Grace Choi's beauty filters don't do that — instead, these filters aim to simply help you learn how to apply real-life makeup. 

If you're on beauty TikTok, you've probably come across the Contour, Eyebrows, or Eyeliner filters on your For You Page. They're AR filters that place a grid on top of your face. And depending on what makeup you're trying to apply, these filters also have extra, colored lines that serve as handy little guides on where to draw certain makeup techniques. 

Choi married her personal love of makeup with her professional career by inventing Mink, the world's first 3D makeup printer, in 2014. "Throughout my 10 years or so in beauty technology, I've always felt that beauty moments and experiences, including tutorials, could be a lot more personalized and immersive and effective by using AR," Choi told Mashable. 

And yet, Choi never felt like there was a social platform that could properly house this immersive tutorial experience — that is, until TikTok launched an open AR platform called Effect House. Choi joined Effect House, and has since been honing her filter design skills while helping others learn how to apply makeup in a way that's accessible and personalized to each face. She's even expanded beyond makeup filters to experiment with color palette analyzers, personality quizzes, and workout aides.
