Jeju. The largest island in Korea. And birthplace of the latest beauty-boosting ingredients that beauty editors have gone gaga for. The 'Hawaii of Asia' is one of the most unpolluted areas in the world and therefore its indigenous ingredients are purer than those found elsewhere. The volcanic island is largely made up of solidified lava, which makes for a natural and totally transformative ingredient for skin. The ashy soil on the island is the perfect ‘breeding ground’ for a large variety of botanicals, which make for the perfect ingredients for effective, super-gentle skincare. Cue no redness.
