What this list is

South Korea's cosmetic ingredient rules are published by the Ministry of Food and Drug Safety in Korean. The English material that circulates is partial, and the gaps are not marked.

  • 1,320 Korean records: 1,077 prohibited, 243 restricted.
  • The regulator is the Ministry of Food and Drug Safety, under the Cosmetics Act.
  • The Korean text is canonical; English versions are incomplete rather than merely later.
  • Functional cosmetics — sunscreen, whitening, anti-wrinkle and others — carry a separate reporting or approval route.

The Ministry of Food and Drug Safety maintains the prohibited and restricted ingredient lists under the Cosmetics Act, and publishes them in Korean. This matters more than the usual caution about translations. The English material in circulation is not a delayed version of the Korean; it is a subset, and nothing in it indicates which entries were left out.

The second thing to know is that Korea separates ordinary cosmetics from functional cosmetics. A product claiming sun protection, skin whitening, anti-wrinkle action, hair loss relief and several other functions falls into the functional category, which carries its own reporting or approval requirement and its own constraints on ingredients and concentrations. A formula that is unremarkable as a cosmetic can move into that category on the strength of a single claim.

The 1,320 records here come from the Korean source. Where a substance has no Korean record, that is the absence of an entry we could resolve, not a finding about the substance.

How South Korea differs from other markets

Comparing this market's imported rules against every other market's for the same substance. A market with no imported rule for a substance is left out of that comparison rather than treated as permitting it.

  1. Search the ingredient by INCI name, CAS number or EC number and record the exact identity.
  2. Open each official source above and check the current version, product scope, concentration limits and required warnings.
  3. Confirm effective dates and whether an English text is official, reviewed or only contextual.
  4. Treat a missing local match as unknown, never as permission or a safety conclusion.
