What it means
The phrase spread through South Korean skincare and social media. The routine behind it is layered hydration: humectants that draw water into the skin, then occlusives that help hold it there.
It has no clinical definition and no standard test. Results depend on skin type, daily sun protection and sleep as much as on any one product.
Also known as
