Korean Skincare Ingredients, Explained
Every Korean skincare routine at Allùre Shop rests on a short list of active ingredients that keep coming back for a reason. Here we explain what each one is: how it works, which skin type it suits, what it pairs with, and which Korean skincare products in our catalog contain it. Read about it before choosing your next serum.
Why this page exists
"Glass skin" is a visible, well-defined skin finish
The Korean beauty term "glass skin" describes an even, well-hydrated surface that reflects light evenly instead of scattering it across dry patches, enlarged pores, or uneven tone. This look comes from a well-supported skin barrier: ingredients that help retain water, calm visible irritation, and support the skin's natural lipid layer over weeks of consistent use, not from a single one-time application.
Niacinamide, Hyaluronic Acid, Centella Asiatica, and Galactomyces Ferment Filtrate are four active ingredients that contribute strongly to this look and form the basis of this encyclopedia. Each section below explains what the ingredient is, how it works, and which products in our catalog contain it, so you can build a routine around function rather than marketing language.
