In Myeongdong, go to Daiso Myeongdong flagship (43 Myeongdong-gil) or

Myeongdong Station (134-1 Toegye-ro), both 10am–10pm. The 본셉 retinol V-fit gel mask is ₩2,000 a sheet with 87K orders, made for the lower face. Nice after a long shopping day. Each sheet is thin and packed alone, so grab extras for friends.
