What order do you apply Korean skincare?

A general Korean order goes thinnest to thickest: cleanse, then toner, essence, serum or ampoule, eye cream, moisturizer, and sunscreen last in the morning. Lighter, watery layers go on first so they absorb, with richer creams and sun protection sealing everything in.
