What is the glass skin trend and how do I achieve it?

Glass skin refers to skin so smooth, hydrated, and luminous that it appears translucent like glass — a trend popularized by Korean beauty. Achieving it requires meticulous hydration layering (essences, serums, sheet masks), consistent barrier-strengthening ingredients like ceramides and peptides, regular exfoliation to remove texture, and broad-spectrum SPF daily. It is more about skin health than any single product.
