Singer Yoon Jisung, formerly of the group Wanna One, is setting the internet ablaze as he shows off a youthful appearance that looks no different from his ‘Produce 101’ days ten years ago.

With news of Wanna One’s reunion, the first episode of the Mnet Plus original reality show ‘Wanna One Go : Back to Base’ featured Yoon Jisung with visuals seemingly untouched by time, astonishing fans. Despite entering his mid-30s, he displayed the warmth befitting the eldest member along with skin that appeared even more ‘rejuvenated’.

In the April 28 premiere of ‘Wanna One Go : Back to Base’, even the members were taken aback by Yoon Jisung’s self-care. Hwang Minhyun praised him, saying, “Jisung, your face looks great today,” then fired a blunt question: “How often have you been going to the dermatologist?”

In response, Yoon Jisung joked, “Do you know how expensive my face is?” When Lee Daehwi added, “Isn’t there a few thousand (ten-thousand-won units) in there?” he quipped, “It’s an expensive face. I’m almost at Pikachu level right now,” indirectly alluding to laser treatments and sending the set into laughter.

After the broadcast, as fans flocked to ask for his care secrets, Yoon Jisung shared his own ‘tearfully diligent’ routine in detail through a fan communication platform.

He said, “I hardly ever order delivery. If you eat greasy food, malatang, and bread day in and day out, it’s hard to hope for good skin,” citing strict diet management as the first key. He added, “Even my YouTube algorithm is all animals or regeneration creams recommended by dermatologists. Only things like, ‘Dermatologists apply only this at home,’ ‘If I reveal this ingredient, dermatology clinics will go out of business’ show up.”

He also said, “At the dermatologist, they only do extractions. After my drama ended, I got ‘Sofwave’ once. I also did facial contouring massage five years ago, but I have severe contact dermatitis and I don’t get much swelling, so my skin actually got worsethough it works well for many people,” and continued, “Other than that, I diligently did the tedious things at home: eating mostly vegetables, using sheet masks and modeling masks, and even layering on collagen packs.”

In response to Yoon Jisung’s revelations, netizens couldn’t hide their admiration. Online communities featured reactions such as, “Among the people I’ve seen in real life, he had the best skinand there was a reason,” “He takes care of himself more diligently than I do as a woman,” and “It’s easy to say, but faithfully following through like that is virtually impossible.”

Meanwhile, Wanna One, formed in 2017 through ‘Produce 101 Season 2’, officially disbanded in 2019. The current reunion includes the members except for Kang Daniel, who is serving in the military, and Lai Kuanlin, who has retired from the entertainment industry. Their reality show ‘Wanna One Go’ is released every Tuesday at 8 p.m. on Mnet Plus.
