She began with the Opéra-Comique de Paris in 1904,[2] dancing in productions of Lakmé (1905), Aphrodite (1906, in which she shared billing with dancer Mata Hari),[3] Ariane et Barbe-Bleue (1907),[4] Carmen (1908),[5] Bacchus triomphant (1909),[6] Le Mariage de Télémaque (1909), Athanaïs (1910), Sapphô (1912),[7][8] La Grande Famille (1914), Un Mari dans du Coton (1916), Les Trois Sultanes (1917),[9] Appassionata (1920), and Le Venin (1923).

She was known for creating the role of Conchita Perez in a stage adaptation of La Femme et le Pantin (1910), in which her very minimal costume was a matter of some scandal.

Her dances were often in the popular exotic style,[13] referencing ancient or "oriental" themes.

Badet does not seem to content herself with the lavish display of her charmingly pretty figure," commented an American writer, "but to run the gamut from the somewhat acrobatic and to our eyes grotesque posturing and 'stunts' which found so much favor with the ancients, to dances of ideas and emotions of a much higher and more poetic order, mingled with passages of adoration of and oblation to the goddess whom she serves.

In 2016, Régina Badet was played by actress Hélèna Soubeyrand in a French film, Chocolat, about the Paris stage of the late nineteenth century.
