Mini bio

How it started.

Born Kim Hyo-jung in Incheon, HYOLYN loved singing and dancing as a child and pursued auditions on her own. She trained at JYP Entertainment before joining Starship and debuting with SISTAR in 2010.

The songs fans grew up with.

As SISTAR’s main vocalist, she helped shape songs such as “Loving U” and “Touch My Body.” She also teamed up with Bora as SISTAR19 for “Ma Boy.” Her solo career began in 2013 with Love & Hate and its title tracks “Lonely” and “One Way Love.”

Building her own path.

After SISTAR disbanded in 2017, she continued through her own agency, Bridge. On “Dally,” she was credited as producer, co-lyricist and co-composer. By 2026, she was releasing through her self-founded ReH Entertainment, returning to the Y2K pop and R&B sounds she loved growing up with OriginaLyn.
