She began her career as a teenager and became one of the biggest box-office draws of the 1930s to early 1940s, appearing in films with political and social themes depicting Filipino patriotism and liberalism.

She was an average student, although her grades fluctuated from time to time. She did odd jobs at bakeshops and sold cookies, siomai and empanada at the movie theaters, which enabled her to watch movie for free.
