US buyers used to INCI names in English find Korean ingredient lists unreadable, because Korean labels transliterate the same INCI names into hangul rather than translating them. The good news is that this makes them mechanically decodable once you know the pattern.
Transliteration, not translation
Korean labels spell INCI names phonetically in hangul. Niacinamide, glycerin and adenosine appear as sound-for-sound renderings. Running the ingredient block through any machine translator usually returns recognizable INCI names, because the underlying words are the same international terms. The exception is a handful of Korean-specific botanical ingredients written with Korean plant names rather than transliterated Latin, which need a separate lookup.
Where to find the full list
Korean product pages place the ingredient list at the bottom of the long scrolling detail section, frequently inside an image rather than as text. Image-based lists defeat browser translation, so use a phone translation app pointed at the image, or check the brand's entry in the Korean cosmetics ingredient database that most brands are registered in. Korean brands are also required to publish full ingredient information on the product page, so if it appears absent it is usually buried in an image lower down.
Concentration is not disclosed
Korean rules, like US rules, require descending order by weight above 1% but no percentages. Brands that advertise a percentage do so voluntarily on the front label. If a hero ingredient appears after the fragrance or preservative block, it is present below 1% regardless of marketing. Products advertising a percentage on the front, such as a stated vitamin C or niacinamide concentration, are generally reliable since the claim is legally actionable in Korea.
Allergen and fragrance flags
Korean labels list the 20-odd fragrance allergens separately when present above threshold, similar to EU practice. If you react to fragrance, look for the tail of the ingredient list where linalool, limonene and geraniol typically appear rather than trusting a fragrance-free claim on the front. Korean labeling also flags a small set of ingredients requiring caution notices, and those notices appear as short bracketed text following the ingredient block.

Are Korean formulas different from export versions?
Usually identical. Where they differ it is because an ingredient is restricted in the destination market, most often certain sunscreen filters.
Do Korean products list ingredients in English at all?
Some export-conscious brands print dual language. Domestic-only brands generally do not.
Is there an official ingredient database?
Korea maintains a cosmetics ingredient reference used by regulators and brands, and most major products can be looked up by name.
