How Hyaluronic Acid works ํ์๋ฃจ๋ก ์ฐ
Hyaluronic acid is a glycosaminoglycan humectant that binds large amounts of water. On skin it forms a hydrated film that immediately plumps the look of fine, dry lines. Larger molecules sit on the surface; smaller fragments distribute within the upper layers. Best applied to damp skin and sealed, so it pulls water in rather than out in dry air.

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.
How long does Korean skincare take to work?
Most skincare, Korean or otherwise, needs time. Hydration benefits can appear quickly, but visible changes in tone, texture or fine lines typically take several weeks to a few months of consistent use, roughly one skin cycle or more. Sun protection and patience matter more than any single product.
