Upon release, the album received mostly positive reviews from music critics; many of them described it as a fun record, although some did not find drastic changes to the original songs.

[2] Lovato's eighth studio album, Holy Fvck, was released in 2022 and described by critics as "her heaviest work yet", drawing from pop-punk and hard rock.

[5] He is credited in all the tracks as the producer, with collaboration from Alex Niceforo, Keith "Ten4" Sorrells, Mitch Allan, Oscar Linnander, Zaire Koalo, Chopsticks, and John Feldmann.

[5] Lovato made Revamped in order to reflect the changes in her life, and stated that it allowed her to reconnect with the songs as she had felt tired of singing them live.

[3] Discussing the album, she said: "I wanted to pay homage to the songs that resonated the most with fans and played a big role in my career by breathing an exciting new life into them.

"[10] Lovato added extra high notes to the songs, that felt that were "easier to record, just because [she has] been singing them for so many years".

[11] Lovato revealed that "Tell Me You Love Me" was the most difficult song to re-record and re-imagine as a rock track, citing its "soulful" sound.

[3] She told Zach Sang that some songs were excluded from the final track listing, including "Get Back" and "Really Don't Care".

[3] Revamped opens with the remix of "Heart Attack", a punk rock song[9] with lyrics about avoiding to fall in love.

[5] "Sorry Not Sorry" is also glam rock,[9] and contains a metal scream in the lyric "Wait a minute", which was not made by Lovato in order to not damage her voice.

[5] "Cool for the Summer" is a metalcore song[9] that starts with synthesizers and static sound before a drum beat and electric guitars are introduced.

[16][17] On July 14, 2023, Lovato released "Sorry Not Sorry" as the first promotional single from the album and subsequently announced Revamped on her social media accounts.

[20] At the 2023 MTV Video Music Awards, Lovato performed a medley of the remixes of "Heart Attack", "Sorry Not Sorry", and "Cool for the Summer".

[39] Stephen Daw from Billboard described Revamped as "the work of an artist taking the narrative back from her years of pop stardom".

[40] Lovato's vocal performance was highly praised by critics,[5][3] with American Songwriter's Alex Hopper calling them "strong as ever".

[14] Vicky Greer from The Line of Best Fit agreed, while writing that the album was a disappointment and a "musical step backwards in [Lovato's] career", containing missed oportunities.
