Kiehl’s has been one of our go-to skincare brands for years for a multitude of reasons. Not only does Kiehl’s offer a wide array of products — from heavy duty moisturizers to brightening face masks and highly concentrated serums, but it has also been a trusted brand for over 150 years. Founded in 1851 in New York City, Kiehl’s started as a pharmacy and over the years evolved selling teas, tinctures and herbs before delving into the world of skincare. Some of the classics we still know and love were first introduced in 1962 (like the Ultra Facial Cream, Blue Astringent Lotion and Calendula Herbal-Extract Toner). Today, the brand remains a dermatologist-favorite skincare brand, with thousands of five-star reviews and products that have stood the test of time.
