CORTIS member Seonghyeon has become the subject of plastic surgery allegations after a viral online post claimed to have identified what appeared to be a surgical scar on his nose.
The discussion began when a netizen shared close-up photos of the idol and pointed out what they claim to be evidence of surgery.
“Looking closely, I can see what looks like an open rhinoplasty scar.”
The poster went on to speculate that Seonghyun may have undergone multiple nose procedures, including a nasal septum extension and nose bridge reshaping, though no evidence beyond visual speculation was provided.
Pre-debut Seonghyeon
The netizen further compared Seonghyun’s pre-debut and current appearance, commenting, “Before debut, he had monolids and a rounder, flatter nose. Now his nose is much higher and his visuals have completely transformed.”
The post quickly spread across social media and online communities, sparking debate among fans.
