Deep Sea Water

Ulleungdo
pronounced wool-leung-doh

Ulleungdo covers the Ulleungdo and Dokdo island regions at the farthest eastern end of the Korean peninsula. Our Dokdo line was formulated with the deepest sea water that was ever used in skincare history. Extracted from 5,000 ft. deep off the coast of the East Sea, our deep sea water is incredibly rich with natural minerals (90+), impeccably preserved, and perfectly balanced for our skin.
