from the Kiehl's website :
Kiehl's since 1851
At Kiehl's, our products are made utilizing the finest ingredients known to us in our unique formulations to assure the high quality skin, hair and body care that our customers have come to expect from us for more than 150 years. Our unique, extensive background represents a blend of cosmetic, pharmaceutical, herbal, and medicinal knowledge developed and passed on through the generations. Through the most advanced technology, we incorporate this knowledge into the formulation of our products.
Kiehl's does not advertise (although our retail partners may choose to feature our products in this way). We utilize only simple, efficient, recyclable packaging so that we may concentrate our efforts and costs on what is truly important: the substance and quality of our products. Truthfully, only the ingredients can help your skin.
We encourage you to read our product labels. The more you know about ingredients, the better you will appreciate Kiehl's products. We refrain from hyperbole and make no false claims. On the contrary, we strive to uphold the standards of honesty, fairness, and integrity that have come to characterize Kiehl's and to gain the confidence of our friends around the world. We have gained our position based on our reputation and on recommendation. We prefer to reach you through the quality of our formulations and the personal attention that we pay to our customers' needs.
