In her half-century of artistic works, she garnered over seventeen awards of national and international recognition. Hoyos began her career as a teacher, at the University of the Andes, where she taught from 1961 to 1965.[3] She began exhibiting in 1966 and in 1967, won the second prize at Bogotá's Museum of Contemporary Art (Spanish: Museo de Arte Contemporáneo de Bogotá) Young Painter's Biennial. The following year she took first place in the Bogotá Museum of Modern Art's "Environmental Spaces" exhibition. In the latter part of the 1960s, she produced Pop Art works and by the 1970s, was working in a minimalist style producing abstract works. These led to the creation of her first series, Ventanas (Windows), which many consider her most important works. The oil paintings were small with a square presentation, utilizing vertical and horizontal lines to frame an abstract landscape.The window was a device to focus the view on a frozen moment in time, typically depicting a landscape image, with the frame itself representing the separation of the internal and external reality. In her later works in this series, the framed image becomes more obscure and it is impossible to determine if one is looking in or out of the window.
