  • Summary
  • - ‘Cosmetics’ refers to products applied externally to enhance or brighten appearance or maintain or improve the skin and hair by cleaning and beautifying the body, and has a relatively weak interaction with the body. Articles included as medicine specified in Paragraph 4, Article 2 of the Pharmacy Act are excluded.
  • - ‘Efficacious cosmetics’ corresponds to each item below, referring to cosmetics specified by Ministry of Health and Welfare decree.
  • * Products contributing to skin whitening
    * Product contributing to wrinkle reduction
    * Products contributing to tanning or UV protection of the skin
  • Related Quality Testing
  • - If cosmetics manufacturers or importers consign quality testing of manufactured or imported cosmetics to a quality test organization designated by Korea Food and Drug Administraton conforming to the Cosmetics Act Article 17, they may not be equipped with the laboratories, facilities and tools necessary for quality improvements (Cosmetics Act Paragraph 4, Article 5)
  • - A person who intends to manufacture or import effective cosmetics should have each item examined for safety and efficacy by the Korean Food & Drug Administration (Cosmetics Act Article 4, Safety Evaluation). Cosmetics that have not be examined should not be manufactured, imported, stored or displayed for the purpose of sale nor be sold as specified by Article 13 (prohibition of manufacture and sale).
  • - Cosmetic manufacturers or importers should carry out thorough quality testing to check that the cosmetics they manufacture or import meet the standards specified by the Cosmetic Act, draw out and furnish a quality management document, and preserve it for 3 years from the date of manufacture (import). For import/manufacturing companies without their own testing facilities, importers passing customs entry or manufacture, request testing from the Korean Testing & Research Institute designated as a consignment test organization for cosmetics quality management and may sell the products if there are no problems with the test results.
  • - Quality inspection and management
       1) Quality inspection : after manufacture or during import, receive an EDI and conduct testing
                         [cosmetic quality inspection request for]
       2) general quality management : after manufacture or before and after import, test for quality management
                               [general quality management home-delivery application request form]
