ZERONATE X KWANGTAE KIM
Rising to fame as a standout flirt on EXchange 3,
KWANGTAE KIM has captivated audiences with his expressive and unfiltered charm.

At the center of that expression is, ultimately, his ‘smile.’
The detail that completes his overall impression—within it lies the choice of ZERONATE.
Q1. Hello, could you introduce yourself?
Hello, my name is KWANGTAE KIM, and I starred in EXchange 3.
Q2. How have you been since the show?
A lot of people ask if I quit my job, but I haven’t. I’ve returned to my normal routine, working hard at my job, while also appearing on various shows and actively engaging with people through YouTube and social media.
Q3. How did you feel seeing yourself on TV or YouTube?
At first, it felt really awkward. Especially during close-up shots or eating scenes, and even when I smiled, my teeth were much more noticeable than I expected. That made me very conscious about them.




Q4. What made you choose ZERONATE?
As a sales manager, interacting with people is a big part of my job, and I realized how important teeth are in those situations. At the same time, I didn’t want anything that looked too artificial, as it could feel overwhelming to others. I was looking for a natural change, and after exploring different options, I felt that ZERONATE offered a subtle and natural transformation. That’s why I chose it.
Q5. What were you most concerned about before the treatment?
I wasn’t worried about the results because I had heard a lot of positive feedback. However, I hadn’t experienced much dental treatment before, so I was concerned about possible pain. But once I went through it, I could hardly feel anything—it was virtually painless and very comfortable.

Q6. What kind of reactions did you get afterward?
My friends said that something had definitely changed—they told me I looked cleaner and more put-together. I think it’s because of ZERONATE. Not only my friends, but even at work, people say I look more polished and that I make a better impression, which feels great.
Q7. What would you say to those considering ZERONATE?
I spent a long time thinking about it too, but I’d recommend not overthinking it and just going for it. I used to feel awkward when I smiled, and I thought it was because of my teeth. After the treatment, I can now smile with confidence. So if you feel self-conscious about your smile, I highly recommend it.
Q8. How would you describe ZERONATE in one phrase?
I’d compare it to white truffle. When you add white truffle to a dish, it elevates the overall quality—almost like a three-Michelin-star experience. That’s how it felt for my smile, like adding a refined finishing touch. I’m extremely satisfied.
