f(x)'s Krystal updated on what she's been doing as of late while appearing at an event for a cosmetics brand in China the other day.

"I am currently filming a movie in Beijing and I plan to go into a drama soon," she said. "I've been going back and forth between China [and South Korea]."

When asked how she maintains her good looks, she said, "Firstly, I eat and sleep well, and living with regularity is good, but I am a bit irregular.  I exercise a lot, and sleep is the most important.  I replenish my fluids and do face masks to take care of my skin."

Krystal even talked about makeup with, "I usually prefer extremely natural makeup, so I barely wear any.  When it's necessary, I use a powder cushion."

As for future plans, she said, "There will probably be a growth in Chinese promotions in the future and I think I'll be seeing everyone more often.  Please give me a lot of support and I hope that you will have a lot of anticipation."
