Glass skin is a term used to describe exceptionally smooth, even-toned, and lustrous skin that appears flawless and has the appearance of glass. It is a Korean beauty skincare trend that aims for an intensely moisturized skin that gives off an almost transparent complexion and a "very youthful, lit-from-within glow". Achieving glass skin requires a multi-dimensional approach, including a solid skincare routine that will help the surface of the skin become extremely smooth, without bumps or rough texture, and directly beneath the surface, there should be a large amount of water to create the moist and lustrous appearance that catches and reflects light. Finally, the skin should look plump and firm. Hydration and protection are arguably the most important steps in the glass-skin routine, and it is essential to keep everything gentle and avoid overdoing it with too many acids or harsh actives. Glass skin doesnt happen overnight, and it takes time to achieve that next-level clarity and smoothness.
