Gomez collaborated with various producers, such as Albert Hype, DJ Snake, Jota Rosa, Maro, Neon16, and Tainy, to achieve her desired sound.

The EP was supported by three singles: "De Una Vez", "Baila Conmigo" with Rauw Alejandro, and "Selfish Love" with DJ Snake, and is Gomez's first project to be prominently in Spanish language.

Upon release, Revelación received acclaim from music critics, who highlighted its tasteful production, and praised Gomez's expansion of her artistry.

[8][10] Gomez hired Leyla Hoyle-Guerrero, a language coach, to help restore her Spanish vocabulary, work on her accent, and practice her slang.

Her first venture into Latin music since the release of the Spanish-language version of her former band Selena Gomez & the Scene 2010 single "A Year Without Rain", titled "Un Año Sin Lluvia", she described the song as "a beautiful love anthem".

[34] AllMusic's Matt Collar found Gomez remaining "artistically fearless" on Revelación, by taking up her Latin roots and sophisticating her pop sound furthermore, which ensued in a "romantic atmosphere that balances chic studio-cool with warm vulnerability".

[11] Hannah Mylrea of NME stated that the EP replaces "all-out pop belters" of Gomez's older catalog with "tasteful R&B and reggaeton" that shine new confidence.

[12] Entertainment Weekly writer Marcus Jones wrote that the project succeeds in establishing Gomez's ability "to toe the line", as she does not fully embrace urbano, but adds her own twist to it.

[13] Rolling Stone critic Lucas Villa viewed Revelación as Gomez's "captivating flirtation" with Latin music, through which she discovers "her groove among the reggaetón beats".

He praised Gomez's "ASMR-ready" Spanish vocals as "alluring", and Tainy's "masterful" production that blurs the lines between pop and Latin music scenes.

She picked "De Una Vez", "Baila Conmigo" and "Selfish Love" as the best tracks, while dismissing "Buscando Amor", "Dámelo To" and "Adiós" as outdated.
