Kiehl's is primarily a 'state of mind', a way to deal with cosmetics that are very specific Kiehl's. The family that made Kiehl's great, developed the products in cooperation with the expectations of the consumer. The history of the brand is officially part of American history: more than a hundred products belong to the collection of the Smithsonian Institute in Washington (Museum of American History). Almost 160 years later, Kiehl's is more popular than ever. Undoubtedly because the brand never deviated from the original values: scientific research, quality and a great respect for customers and the community.
