A Harlem woman is suing M.A.C after she allegedly contracted herpes from a lipstick endorsed by pop-star Rihanna. The ruby red lipstick—"Riri Woo"—has been promoted by M.A.C in pop-up shops at the singer's concerts. “I wasn’t able to work for two weeks. It cost me a lot of money,” said 28-year-old Starkeema Greenidge, a waitress in New York who tried the product on at a M.A.C pop-up shop on May 7. Greenridge says the company needs to improve its sanitary practices immediately if it wants to prevent further infections. “This is going to happen over and over again if nothing is done,” she said.
