I use this as my morning essence to save my SK-II for evening use -- applied after my green tea toner, it's a good tandem as my "base" under my sunscreen. I use Beauty of Joseon sunscreen which is quite emollient for my combination skin so I treat that as my moisturizer. Without sunscreen, I still top this essence with moisturizer after. So far, my skin has been clearer & plumper than usual even with just these simple steps.
