Free shipping and returns on Kiehl's Since 1851 Ultra Facial Cream at Nordstrom.com. What it is: A lightweight facial cream that provides 24-hour hydration.Who it's for: All skin types.What it does: Formulated with imperata cylindrica and Antarcticine, this beloved moisturizer leaves skin feeling comfortable and well-balanced, even in severe weather conditions. Antarcticine, sourced from Antarctica, is a glycoprotein known to moisturize dry skin. With cryoprotective (protection against freezing) properties, Antarcticine is known to help defend and hydrate skin in extremely cold temperatures by facilitating the retention of natural moisture reserves. The roots of imperata cylindrica (desert plant extract) contain high concentrations of potassium, which is known to provide immediate and lasting hydration for dry skin. Native to many of earth's deserts, this plant is especially prolific in the Australian Outback and is believed to have been used as a substitute for salt by indigenous Australians of centuries past. Squalane, a signature Kiehl's ingredient, is a highly refined botanical lipid derived from olives. With exceptional affinity to skin, squalane absorbs easily and is known to help replenish skin's moisture barrier, keeping it soft, supple and moisturized. How to use: Apply a dime-sized amount to your fingertips and massage onto your face morning and night or as needed to smooth and moisturize skin.
