Glass skin isn’t a filter, it’s a routine
Glass skin is shorthand for skin that looks clear, even and softly luminous from within. It isn't a trend or a filter, it's the visible result of patient, layered hydration.
The Korean approach treats the barrier first. Low-pH cleansers, alcohol-free toners, then essences and serums to draw water into the skin before sealing it with a light cream.
Done daily, the effect compounds. Within four weeks most skins look calmer, more even and quietly reflective in natural light.
