In Korean routines, “toner” usually means a hydrating, watery step rather than the stripping astringents of the past, and an “essence” is a lightweight, often slightly more concentrated hydration or treatment layer. The line between the two is blurry and brand-dependent, so it helps to think in terms of what a product does — hydrate, exfoliate, or treat — rather than its name. Below are the main types, with honest notes. Introduce one at a time and patch test.
