Actor Choi Kang Hee from 'Problem Child in House' revealed her secret to looking youthful.

In the KBS2TV entertainment program 'Problem Child in House' aired on the 5th, actor Choi Kang Hee, who fits the keyword of youthfulness, appeared. Choi Kang Hee revealed that she is the same age as Hong Jin Kyung, shocking everyone.

Additionally, Kim Jong Kook noted, "My older brother is a plastic surgeon. He told me to try it since the hospital has the machine. So, I got a lifting procedure," cheerfully explaining why he looked particularly youthful today, which brought laughter.

Choi Kang Hee had to reveal her own secret to looking youthful. He seemed a bit shy, saying, "There really isn't a secret to looking youthful. I just don’t wash too often and I also don't sweat much," expressing his belief that he minimizes skin irritation.

Choi Kang Hee shared another tip, saying, "I pour skin toner onto inexpensive cotton pads and make a mask to put on whenever I have a moment," to which Yang Se Chan tilted his head and responded, "It doesn't seem like a particularly special tip, does it?"
