SQUALANE A signature Kiehl’s ingredient, Squalane is a highly-refined botanical lipid derived from sugar cane. With an exceptional affinity to skin, Squalane absorbs easily and is known to help replenish skin’s barrier keeping it soft, supple and moisturized. In our formulations, Squalane is renewable and responsibly sourced. GLACIAL GLYCOPROTEIN Originally sourced from Antarctic Sea glaciers, Glacial Glycoprotein within our formulas helps to deeply hydrate and maintain skin’s moisture balance. Each time our Glacial Glycoprotein is produced, it’s done in an environmentally friendly manner, without further extraction of the glaciers, making this skincare ingredient a renewable raw material.
