Drouin was a versatile actress, which was not common during a time when most actors specialized in their one category of roles. She shared the tragedy and princess roles with Jeanne-Catherine Gaussem and the heroine roles with Marie-Geneviève Dupré, as well as the soubrette roles with Marie-Anne Botot Dangeville. When Marianne-Hélène de Mottes and Marie-Anne Pauline Du Mont retired and Mademoiselle Camouche (Jacqueline Camouche) died, she took over the character roles, in which she dominated for her last twenty years onstage.
She was also a good singer and was able to take on singing roles.
Drouin is also remembered for being the first woman allowed to hold the opening speech and prologue before a show on the Comédie-Française, which was a controversial thing in its time.
