: Following the success of Virgin People , Castillo leaned into the "pene star" persona, starring in a string of controversial films alongside other popular actors of the genre. In a 2022 interview, Castillo reflected on this career pivot, stating she had "no regrets." For her, it was a practical decision—"Kailangan kumita ng pera... hindi lang naman ako ang naging sexy star, marami kami" (We needed to earn money... I wasn't the only sexy star, there were many of us).

After a period of working abroad in Japan and Guam as a singer, Castillo returned to the Philippines and resumed her acting career, focusing on supporting roles in popular television series.

By the late 1980s and early 1990s, Castillo expanded her footprint in the industry by taking on roles in action cinema while simultaneously stepping into the role of a producer.
