Emulsion
Emulsion — a lightweight, milky moisturizer that blends water and oil into a fluid, easily absorbed texture. Common in Korean and Japanese routines, it provides hydration and light conditioning without the heaviness of a cream, making it a popular choice for normal, combination, or oily skin.
Key points
- Technically, an emulsion is a stable mixture of water and oil, which is why the texture is fluid and milky.
- It is lighter than a typical cream and absorbs quickly, leaving minimal residue.
- It is usually applied after serums or essences and can serve as the moisturizing step in a routine.
- Its light feel makes it well suited to warmer climates or skin that finds richer creams too heavy.
