Her works were featured in various international shows, among them the first Exposición Anual de Pintura, Dibujo y Escultura (Annual Exhibition of Painting, Drawing, and Sculpture) for artists of South America in 1893.

[2][9] After returning to Buenos Aires, Belín Sarmiento studied art under José Agujari, a renowned painter who was also the first teacher of her contemporary, artist María Obligado.

[11] In addition, she painted classical portraits of notable figures of the time such as Dalmacio Vélez Sarsfield, Francisco Muniz [es] and José María Estrada.

[12] As of 1885, she was contracted by the government of the province of San Juan to paint portraits of Salvador María del Carril, Antonino Aberastain [es], and Francisco Narciso de Laprida.

[13] She also painted portraits of women, with her feminine subjects appearing very similar to the models used by the French painter Charles Joshua Chaplin.

She frequently exhibited works alongside contemporaries such as Julia Wernicke and Maria Obligado, and won her honorable mention awards in 1894, 1895, and 1898, along with a prize in the 1910 Centenary Exposition [es] in Buenos Aires.

For example, the art critic Eduardo Schiaffino focused almost exclusively on the artistic influence of Domingo on his granddaughter over the fact that Eugenia had been a student of her aunt Procesa Sarmiento, who was a notable painter in her own right.

The exhibition was part of a pioneering effort to uncover the hidden work of over 250 Argentinean female artists, historic and contemporary, in national, regional and private collections.
