Bajo un mismo rostro (English title: Single Identity) is a Mexican telenovela produced by Christian Bach and Humberto Zurita for Televisa in 1995.

Irene Saldívar is a young woman, beautiful and rich, who suffers a great emotional shock after the death of her father and brother.

But the reality is different since Carlos is an ambitious and unscrupulous man who pretends to be a good person before his wife, Luciana Mendoza, and Irene herself.

Irene, who has become pregnant with Alexis's baby, returns heartbroken to Mexico, and there she receives the help of Diego Covarrubias, the doctor who treated her father and brother when they died.

They both fall in love, but new obstacles appear: Estelita, Diego's sickly daughter, is too attached to the memory of her late mother Magdalena and refuses to let another woman take her place.
