WHAT “GLASS SKIN” MEANS
Glass skin describes skin that looks clear, smooth, well-hydrated and luminous. It is a beauty expression for a dewy appearance, not a literal skin type.
The Korean beauty phrase explained without the hype — what people usually mean when they use it.

Glass skin describes skin that looks clear, smooth, well-hydrated and luminous. It is a beauty expression for a dewy appearance, not a literal skin type.
The look is usually associated with gentle cleansing, layers of hydration, moisturizer and sun care. Makeup can add a luminous finish, but skincare is usually the main idea behind the term.
Real skin naturally has pores and texture. In Korea, the phrase is best understood as a goal of healthy-looking hydration and glow rather than perfectly reflective skin.
