Song Joong Ki gave a more serious answer, saying, "When I contract with a cosmetics brand, I usually use their products. I alway wear sunscreen and use facial masks every day." 

On the other hand, Song Hye Kyo said, "When I'm not working, I got to the dermatologist and get skin care treatments. I can't go when I'm filming so I carry around facial masks and always apply them before going to sleep."
