Singer Sung Si-kyung has been tapped as a beauty brand model for the first time since his debut, unveiling a striking transformation.

On the 1st, Sung Si-kyung posted several photos to Instagram, writing, "It’s my first beauty modeling gig, so I’m shy, but it’s fascinating and I’m grateful." He continued, "I hardly even used toner or lotion before, but now I even know the exact order to use the products," adding, "Thanks to this, I’m paying much more attention to skincare. It feels like a great turning point in my life."

The photos show noticeably smoother skin and a softer vibe that instantly caught attention. Posing naturally while holding various products, he showcased a fresh appeal that goes beyond his image as a ballad singer.

His casting reportedly came after rigorous self-care. To prepare for the commercial shoot, Sung Si-kyung combined a strict diet with workouts to lose weight, revealing, "I managed myself so intensely that I worked out three times a day." He also surprised fans by admitting he stuck to a diet of eggs and sweet potatoes.

Meanwhile, Sung Si-kyung currently meets viewers through the KBS2 music talk show The Seasons - Seong Si-kyung-ui Gomaknamchin. He is also set to hold a branded concert titled 'Chukga (Wedding Song)' at Yonsei University’s Outdoor Theater in Seoul on May 2–3.
