Thomas had previously contributed uncredited vocals on the band's first two Spanish albums, only using a pseudonym when co-writing the track "Liso, Sensual" from Nuestro Amor.
"No Pares" was written by Mexican singer-songwriter Lynda Thomas, with production from Carlos Lara in its studio version, which contains pop rock stylings, and features the voices of the two alongside bandmate Maite Perroni on the choruses.
In the third verse, Dulce pleads "No construyas muros en tu corazón" ("Don't build walls in your heart"), before adivising "Lo que hagas siempre hazlo por amor" ("What you do, always do it for love").
She motivates the person with the lines "Pon las alas, contra el viento / No hay nada que perder" ("Put your wings, against the wind / There's nothing to lose").
The video was edited to promote "No Pares" on many music channels and cut down to around one mintue and a half to serve as the fourth opening for the third season of the telenovela Rebelde.
