Hydration & barrier

Hyaluronic acid

also known as Sodium hyaluronate

The water magnet — pulls moisture into the upper skin layers for instant plump.

What it actually does

Hyaluronic acid is a humectant — it binds water molecules and holds them where you want them. Korean formulas tend to layer multiple molecular weights so it hydrates at different depths in the stratum corneum. The visible result is bouncier, plumper skin within minutes, which is why it's the backbone of nearly every K-Beauty essence.

Who it's for

Everyone, all skin types. Dry and dehydrated skin gets the most obvious benefit; oily skin benefits too because dehydration often drives overproduction.

How to use it

Apply to damp skin and seal with a moisturizer on top — that 'damp skin → humectant → occlusive' sequence is the whole point. Used on bone-dry skin in dry air, humectants can pull water out of deeper layers instead of in.
