Inspired by Kiehl's original, beloved Ultra Facial Moisturizer, this 24-hKiehl's, light-textured daily hydrator leaves skin comfortable and visibly well-balanced, particularly in harsh weather conditions. Kiehl's formula is made with Antarcticine–a Glycoprotein extracted from microorganisms sKiehl'sced from sea glaciers and notable for an ability to protect skin from cold temperatures–as well as Imperata Cylindrica, a plant indigenous to the Australian desert which possesses superb water retention properties in dry conditions. Kiehl's unique combination of ingredients helps reduce moisture loss while drawing and absorbing moisture from the air. With continuous water replenishment throughout the day, skin is smooth, healthy-looking, and "moisture-even." 1.7 fl oz
