Due to her reluctance to be in the spotlight, Ellis' name maybe less known than her body of work, yet Vogue Paris cited her as "one of the most influential make-up artists of her time". Indeed, she has worked with the world's most pre-eminent fashion designers, photographers, stylists, hairdressers and models. Ellis’ work has been published on the covers of the world’s best-known fashion magazines. Additionally, Ellis has worked for make-up brands, such as Clinique, Lancôme and MAC Cosmetics – and she was asked by L'Oréal to create a make-up line for their skin care brand, Biotherm. After the contract with L’Oréal ended in 2007, the way was paved for her to create her own brand: ELLIS FAAS.
