Girl group SECRET's member Hyosung revealed her naked face.

On January 5, Hyosung posted on her Instagram, "It must be the Monday disease, I'm already sleepy. I'm gonna go to sleep listening to 'Goodnight Kiss'" along with a picture.

In the picture, Hyosung is revealing a completely different face from when she has full makeup on for the stage. She has flawless pale skin and natural wavy hair.

Internet users who saw this commented, "Even your naked face is so pretty," "Is this really Hyosung?," and "Looks so innocent without  makeup on."
