This episode we welcome Balanda Atis, chemist and Manager of L'Oreal's Women of Color Lab. 

"Atis grew up to be a cosmetic chemist — she's worked at L'Oréal for 17 years — and in 2006, she embarked on a new project: reformulating foundation for women of color. Over the next seven years, in the quest to develop shades and textures suitable for darker complexions, Atis and her colleagues took skin-tone measurements from more than 1,000 women representing 57 countries. Ultimately, the team helped L'Oréal launch more than 30 new shades.
