How to read a Korean skincare label (even if you don't read Korean)

On a Korean cosmetic label, every ingredient is printed in a standardized Korean name and listed in descending order of concentration — with everything present at 1% or less allowed in any order after that [1]. That single rule, set by Korea's Ministry of Food and Drug Safety, is the key to the whole label: the first few names are most of the product, and the long tail near the end is mostly actives, preservatives, and fragrance at fractions of a percent. Learn to read position, and you can size up a Korean product you can't phonetically pronounce.

FAQ

Do Korean labels list ingredients in order of concentration?

Yes — down to 1%. Korean regulations require all ingredients to be listed in descending order of concentration; ingredients present at 1% or less (plus colorants and fragrance) may then be listed in any order. So the first several names are the bulk of the formula, and the order among the tail end is not meaningful.

What does "정제수" at the top of a label mean?

It means purified water, the solvent most skincare is built on. Water leading the list is completely normal for a serum, essence, toner, or lotion — it isn't a sign of a cheap or "watered-down" product; it's the base almost every water-phase ingredient is dissolved into.

Are Korean ingredient names different from the ones on Western products?

The Korean text is different, but the underlying names map to the same shared standard, INCI, used on labels worldwide. Niacinamide, hyaluronic acid, glycerin, and ceramides are the same molecules with Korean spellings. A decoder converts the Korean name to the INCI name so you can compare directly against a Western label.
