The bestselling Kiehl's Creamy Eye Treatment With Avocado ($30-$48) uses natural ingredients including beta-carotene (an antioxidant found in many orange and red vegetables), shea butter (from the fruit of the African Karate tree), and avocado oil (from the fruit, of course). While 36 percent of their formulas contain at least one sustainably sourced raw material, Kiehl's is committed to upping this to at least 50 percent by 2020.
