Faltan Lunas was well received by the Latin public and critics, and, when released, became "Album of the Week" at Mixup, the most important music store in Mexico, for its high sales.

Due to the failure of the album, Fey seemed to disappear, making no appearances in promotional events, concerts or television shows.

Y Aquí Estoy reached the top 10 thanks in part to digital sales and #1 in Colombia, thanks to which the album was released in the Latin American country.

The promotion of the album was reduced to several TV performances in Mexico and the United States, during 2006, where she repeatedly performed her lukewarm hit "y aquí estoy" as well as the songs "Me has vuelto loca" (which was intended to be the second single) and "como un ángel", in addition to the hits from her previous album "La fuerza del destino", such as "Barco a venus".

As a curiosity, the original versions of the songs "Faltan lunas" and "Volar otra vez" were written by Graeme Pleeth, who worked on Fey's 2002 album "Vértigo".
