I don't use Beauty of Joseon Serum ever other day, it's very rarely when I do a skin rotation. The same goes for the Rice Toner. I use it whenever I want to take a break on a product. For example, when I don't use the 2% BHA Liquid Exfoliant, I'll maybe use the the Joseon Serum. Still, very rare when I do but I still added them to my skin care since I do somewhat use them.
