Actress Kim Sung-Ryung has revealed the side effects of an eye mask. She posted selfie photos on her Instagram with a message saying, "I fell asleep for 5 hours wearing an eye mask (the instruction said to wear for 15 -30min). Still, I didn't expect it to go this far."

She added, "I was like a monster last night because of the swollen eyes. In the morning, I went to the hospital, got a shot, take medicine, put ointment, and came back like this. The first performance of 'Misery' at Ulsan, of course, the production is more important, but I am sorry I couldn't show all the best images."

In her photos, the cheek under her eyes can be seen red swollen along with the shape of the mask. Many comments left comforting and encouraging messages like, "You are still pretty. It's ok," and "I wish you get well soon."

Meanwhile, Kim Sung-Ryong has been playing Annie Wilkes in the theatre 'Misery' in Ulsan since the 4th.
