What is hyaluronic acid and how do you use it?
Hyaluronic acid is a humectant that draws water into the skin for a plumper, hydrated look. In Korean routines it's best applied to damp skin and sealed with a moisturizer on top, so the moisture it attracts stays locked in rather than evaporating.
What are ceramides in skincare?
Ceramides are lipids that naturally make up part of the skin barrier, helping it hold moisture and stay resilient. In Korean skincare they're used to support and replenish a comfortable, hydrated barrier, especially for dry or sensitive skin, and pair well with centella and panthenol.
