Sullyoon설윤설윤
Sullyoon (설윤) is a member of NMIXX, the JYP Entertainment girl group that debuted on 22 February 2022, and is from Daejeon. She hosted MBC's music show Show! Music Core for about two years from 2023 and became Bioderma's brand ambassador in August 2026.
Sullyoon (설윤) is from Daejeon and a member of NMIXX, the six-member JYP Entertainment girl group. She debuted with them on 22 February 2022 with the single album AD MARE, and the agency’s own profile page lists her third of the six. That she is from Daejeon is something she said herself in the Hanwha Eagles’ video ahead of her first pitch for the club in September 2025, and Asia News Agency and Sports Chosun reported it that way.
Outside the group’s releases she has worked as a music-show host. She was an MC of MBC’s Show! Music Core from 15 April 2023 to 15 February 2025, and Sports Seoul looked back on it in November 2025 as about two years of hosting. She has taken a ballpark mound three times, throwing the ceremonial first pitch at the Oakland Athletics’ home game in Sacramento in August 2025, at the Hanwha Eagles’ home game in Daejeon in September the same year, and at the San Francisco Giants’ home game in April 2026.
Three brand relationships are confirmed by reports. In October 2024 le coq sportif chose Haewon and Sullyoon as the models of its 2024 FW campaign; in June 2025 Elizabeth Arden released a Capsule Serum photoshoot with her and introduced her as its ‘muse’; and in August 2026 Bioderma named her its brand ambassador alongside the launch of Atoderm Facial Lotion. At the events of ETRO, H&M, Longchamp and CHAGEE she appeared as an invited guest, and no outlet described her as those brands’ ambassador.
The group’s official YouTube channel is the place to start. K-Culture Radar links to official uploads rather than re-hosting them, so that channel and the Korean music shows are where to follow her.
