She made her film debut in the 1992 film Marriage Story, and released her first studio album, Sorrowful Secret, the same year.

Uhm Jung-hwa officially debuted as a singer in 1993 with her first studio album Sorrowful Secret. By the mid-90s she established herself as one of the top Korean female Singers and entertainers, with a series of hit singles: "Sad Expectation" (Hangul: 슬픈 기대; RR: Seulpeun Gidae), "A Love Only Heaven Permits" (Hangul: 하늘만 허락한 사랑; RR: Haneulman Heorakan Sarang), "Rose of Betrayal" (Hangul: 배반의 장미; RR: Baeban-ui Jangmi), and "Tell Me" (Hangul: 말해 줘; RR: Malhae Jwo).

During the 2000s, Uhm began to focus more on her acting career and committed herself to taking a variety of acting roles. She also began to pursue and experiment with different musical genres, in particular electronica. In 2004, she released her double album Self Control, which featured songs composed by Jung Jae-hyung, Fractal and Roller Coaster. Music critics praised Uhm for her ability to reinvent her image and sound.

Uhm has established herself as one of South Korea's top actresses. She is known for her roles in the films Marriage Is a Crazy Thing, Singles, Princess Aurora, Dancing Queen and Haeundae, which became one of the highest-grossing movies in Korea. She has won two Baeksang Arts Awards for Best Actress, in 2002 for Marriage is a Crazy Thing and again in 2012 for Dancing Queen.

After a two-year break from the music scene, she released her ninth studio album Prestige. Throughout the year she released two singles, "Come 2 Me" and "Song of the Wind" (Hangul: 바람의 노래; RR: Baram-ui Norae), each enjoyed positive critical reception. In early 2007, she won a Korean Music Award for Best Electronic Dance Record.

In the summer of 2008, she released her first EP titled D.I.S.C.O with help from her longtime friend Yang Hyun-suk of YG Entertainment. The lead single "D.I.S.C.O" featured T.O.P, a member from the popular boy band Big Bang. The EP was one of the best-selling albums by a female Artist in 2008, and was further promoted by the digital single "D.I.S.C.O Part 2" which was a remix version of "D.I.S.C.O" and featured G-Dragon, the leader of Big Bang.

Uhm was diagnosed with thyroid cancer but fully recovered after surgery in May 2010. Uhm said she felt a little afraid leading up to the surgery, but rather than being discouraged by the pain she was experiencing, she made up her mind to dedicate herself to helping others by inspiring them. "I want to use my talent and influence in a meaningful way," she said.

After an 8-year-long hiatus Uhm announced that she would be releasing her first new album since D.I.S.C.O in 2008, the album title would be The Cloud Dream of The Nine. She revealed that she would be releasing the album in two parts, the first part would be released on 27th December 2017, and the second part at a later date.

One year after the release of Part 1, Uhm revealed through her Instagram account that she was in the preparation stage of her comeback with part 2 of The Cloud Dream of the Nine.
