I recommend Donginbi 1899 Single Essence.

I've tried all sorts of essences, but this is truly the best. On days when I'm tired all day and my skin feels particularly dry, I apply it and it absorbs instantly, bringing out a glow. I love that shiny, radiant feeling. My husband even said it's good to use after shaving.

I found it better to apply a thin layer before makeup, and a slightly generous amount in the evening.
