About refulgo

Beauty is both material practice and culture. A finish, gesture, formula, or storefront can carry technique, labor, language, and changing ideas of self-presentation. refulgo looks closely enough to hold those layers together, so global readers can appreciate Korean beauty without reducing it to novelty or a shopping list.
