On January 14th, Jung Ji‑so shared a series of recent photos on her Instagram, including newly shot profile images taken on January 12th. In the photos, she showcased a sleek, urban vibe, wearing an all‑black outfit paired with a leather jacket as well as a tailored suit set. She also posted photos of support gifts sent by colleagues from the set of the film Sister, offering a glimpse into her current daily life.
The public reaction was immediate. Many were surprised by how different Jung Ji‑so looks compared to her earlier image in films like Parasite and the Netflix series The Glory. Praise and concern poured in simultaneously, with fans noting that her long‑standing “child actress” image seemed to have completely vanished.
Jung Ji‑so has recently undergone a dramatic style shift, including bleached eyebrows, noticeable weight loss, and long straight hair, all contributing to a more mature and edgy look. As she appeared at major events such as the KBS Drama Awards and the Melon Music Awards (MMA) last year, rumors of plastic surgery began circulating. In particular, online users questioned her sharply defined jawline, with some speculating about double‑jaw surgery.
However, Jung Ji‑so previously addressed her intense appearance management in a roundtable interview in June last year. She revealed that once a project is confirmed, she begins strict exercise routines about a month before filming and limits herself to one meal a day often just chicken breast. She admitted that living this way for a month was far from enjoyable, but necessary for her work.
She also shared an anecdote from promotions for Holy Night: Demon Hunters, explaining that during her first stage greeting, she assumed it would be a casual, photo‑free event and attended without much preparation. Fans later wrote her letters advising her to dress up and wear makeup appropriately for such occasions, prompting her to take styling and diet management more seriously for official schedules.
Because of these explanations, many fans have come to her defense, arguing that her new look is not the result of surgery but rather “a victory of diet and styling,” offering continued support for her evolution.
Jung Ji‑so gained global recognition for her role as Da‑hye in Parasite, and later left a powerful impression as young Moon Dong‑eun in The Glory, portraying the raw pain of a school violence victim. She has since built a steady filmography with projects such as The Cursed: Dead Man’s Prey, Who Is She!, and Holy Night: Demon Hunters, consistently proving her versatility.
Long before acting, Jung Ji‑so trained as a figure skating athlete until her first year of middle school, a unique background that adds to her story. In 2022, she also showcased impressive vocal skills as a member of the project group WSG Wannabe on the MBC variety show Hangout with Yoo.
