Kara Han Seung Yeon once again showed off her youthful face.

On the 22nd she posted on her Twitter "2nd day of weird time schedule because we had to film the move. No please sleep come to me. Be safe and have fun at the end of the year!! Be blessed in the new year. This time blue pin!", along with a photo.

In the photo Han Seung Hyun is wearing a common pin used in hair salons and she's looking straight at the camera. Her clean bare face is unbelievably youthful.

Netizens who saw the photo commented "when is she going to age?", "how does she look so young?", and etc...
