The golden compact Gabrielle (Léa Seydoux) is holding is Poiret Métier de Poiret Poudre Mono.

The red lipstick is by the same brand. I believe it’s Rouge Poiret, but it could also be Rouge Raffiné: the two lipsticks have the same case.

Featuring cosmetics by the historical French maison makes total sense: when the protagonist is shown living a past life in 1910 Paris, she’s a famous pianist. Paul Poiret introduces himself to her and offers to dress her in his own designs. Gabrielle obviously accepts.
