Seo In-young revealed that she underwent arm liposuction and general anesthesia for her ’Waterbomb’ stage performance. She stated that she used her entire appearance fee to cover the procedure costs.

In a video released on the YouTube channel ’Reformed Seo In-young’ on the 22nd, Seo In-young appeared with bruises on her face and arms. She disclosed that she received a skin booster treatment and arm liposuction, saying, ″No matter how hard I diet, the fat on my arms just wouldn’t go away.″ She added, ″The bruises are healing now. I will definitely look prettier by Waterbomb.″

She also expressed her determination for the upcoming ’Waterbomb Sokcho 2026’ stage next month. Seo In-young said, ″I put my life on the line. I paid for it myself. I used all my appearance fees.″ Regarding the results of the procedure, she expressed satisfaction, saying, ″Before, when I bent my arms, there was back fat, but now it’s gone.″

When the production team asked about general anesthesia, Seo In-young explained that the surgery took a long time, so she underwent general anesthesia and removed more fat than expected. She said, ″Still, compared to having had nose surgery five times, this is nothing.″

She also said, ″This Waterbomb lineup is really spectacular. I want to lose more.″ She added, ″Since there are many hot and young people appearing, I felt I needed to at least have a glowing face and slimmer arms.″

She revealed that she did not inform her father about the procedure. Seo In-young said, ″My father told me to remove my nails, so I did, but actually, I had to because of the surgery.″ She added, ″Dad doesn’t know I had liposuction, so this is a big problem.″
