At a school event, Laurent approached Jean-Paul Guerlain, then the head perfumer of the Guerlain family succession of perfumers, and asked him for an internship.[2] Guerlain replied, "Why not?" and so Laurent began her career in the early 1990s working alongside Guerlain.[2] After her three-month internship, she was offered a permanent position at the house, and ultimately stayed with the company for the next 11 years.[2] Her perfumes for Guerlain include Herba Fresca, inspired by early mornings walking barefoot in her grandfather's garden.[2]
Laurent joined Cartier in 2005.[4]
In 2006, Laurent created Cartier's fragrance Baiser Voler, and launched L'Heure vertueuse in 2012.[2]
In her 2015 Cartier work L'Heure perdue, Laurent used exclusively lab-created molecules, seeking to "shatter the idea that the result had to be hard, abstract, aggressive." Writing in Le Monde, Claire Dhouailly described the creation as just the opposite of this stereotype of synthetic ingredients, a fragrance that instead felt "soft, caressing, almost maternal."[5]
In 2016, she created Cartier L'Envol,[6] the scent used in the 2017 installation "OSNI 1- Le Nuage Parfumé" ("Unidentified Fragrant Object 1- the Perfumed Cloud") at Foire Internationale d’Art Contemporain (FIAC).[7][8]
Also in 2016, Laurent launched a line of oud fragrances for Cartier called Les Heures voyageuses.[9] The collection has six fragrances, including Oud & Santal, Oud & Musc, Oud & Oud, and Oud Radieux.[10]
With Jean-Claude Ellena and Sylvaine Delacourte, Laurent is one of 16 perfumery experts who oversee the Grand Musée du Parfum in Paris.[11]
