As a chemist at the company
Playtex Products, Atis worked on various brands of
personal care products including Banana Boat, Jhirmack, Ogilvie, and Tan Express. When she joined
L'Oréal USA in 1999, she first worked on
mascara formulations. Not satisfied with existing makeup for dark-skinned women, in 2007, she started a side project at her job with the permission of the head of the company's makeup division. Atis and two other L'Oréal scientists went to shows hosted by the company across the United States and collected skin color measurements from women of color. Through her research at the company, she discovered that
ultramarine could be utilized in
foundations to create rich and deeper shades while avoiding the muddy finish common in existing products for
dark skin tones. Atis was made manager of a laboratory opened by the company in 2014 dedicated to developing cosmetics for a range of skin tones. In October 2020,
Elle magazine named Atis one of "10 Black women making history" and identified her as the "driving force" behind the expanding range of makeup shades—to accommodate all Black skin colors—in brands like
Armani,
Lancôme,
Maybelline, and
Urban Decay. ==References==
