Karolina worked at the theatres Djurgårdsteatern and Nya Komiska Teatern before she was hired at the Royal Dramatic Theatre in 1814. She worked there for fifty years, and became one of the most popular actors there. But she never became a star because of the parts she played; she always played old women in comedys, never heroines and main parts. She was very well used and never lacked parts to play, but she was not given main parts. It was said, that she had a rare quality; she knew her limitations.
