Towards the end of 1994, her mother was working on a deal with Argentina's largest television company, Telefe, to create a children's soap opera. "Chiquititas" was the story about the life of a group of orphaned children living in a manor known as Rincón de Luz. Yan starred in the show as Belén, the orphan house's director and a mother figure to the orphans. She also portrayed Belén on stage, in the show's annual musical presentations. "Chiquititas" catapulted Yan's celebrity status outside Argentina. She retired from the series in 1998, taking a hiatus before returning to Argentine television in 2000, when she played "Jessica" in one chapter of the suspense television program, "Tiempo Final" ("Final Moment"). She collaborated in 2001 alongside Susana Giménez in a variety show named after the latter.
