On the August 23 airing of 'Kim Chang Yeol's Old School', Red Velvet joined as the guest. When asked what changed since their debut, Yeri answered, "My skin has changed. When we first debuted, I didn't have any skin troubles even if I wore makeup every day."
She then revealed, "I went to the dermatologist today and got extractions. I'm starting to breakout. I'm only thinking about my skin now. So I'm also kind of afraid to stand in front of the camera."
