In her six decades in Argentine entertainment, at the time of her death, she had filmed over thirty movies, premiered twenty plays, had nine television appearances, completed three radio series and had had countless appearances in print media. She was one of the singers who emerged in the 1920s along with Azucena Maizani, Libertad Lamarque, Ada Falcón, and Rosita Quiroga, who created the female voices of tango. She was primarily remembered for the songs "Se dice de mí" and "La milonga y yo".
She began her acting career in theater and may have made silent films. She debuted on the first sound movie produced in Argentina, ¡Tango!, with Libertad Lamarque in 1933. After making a series of films throughout the 1930s, she established herself as a dramatic actress in La fuga, directed by Luis Saslavsky. In the mid-1940s, she moved to Mexico, where she filmed Cinco rostros de mujer, which earned her an Ariel Award from the Mexican Academy of Film.
