In the newly released photos, Jeongyeon confidently shows off her revamped look. She perfectly sports ash-colored hair paired with a chic style, while her noticeably slimmer face and bright images have quickly caught the attention of fans. Many praised her for looking like she had come back to her “first era” I wait.
In 2020, Jeongyeon underwent surgery for a herniated disc in her neck. During treatment she was prescribed steroids, which led to side effects including Cushing’s syndrome. As a result, he experienced rapid weight gain, sparking concern and speculation at the time. The idol later received immense support from fans as he focused on recovery and health.
Now, six years later, Jeongyeon appears healthier and more confident than ever, drawing admiration for both her resilience and her extraordinary transformation.
Meanwhile, TWICE is currently in the midst of their North American tour, part of their world tour “This is for” which includes 35 shows in 20 regions.
