Ingredients are the single most important component of our products, and we at Kiehl's have always proudly displayed ours. Ingredients are not chosen on their aesthetic merit -only formulas with ingredients that are truly beneficial to the skin are selected. We use minimal preservatives in our formulations, just enough to give our products a shelf life. We select many naturally derived ingredients for use in our formulations, and we are committed to utilizing only the most gentle and efficacious formulas at Kiehl's for maximum benefit and results in all of our products. We always formulate our products with the needs of sensitive skin in mind.
