SQUALANE A signature Kiehl’s ingredient, Squalane is a highly refined botanical lipid derived from sugar cane. With an exceptional affinity to skin, this ingredient 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. GLYCERIN Glycerin, a well-known skincare ingredient, is highly compatible and naturally occurring within skin. Within our formulas, it is a powerful humectant known to help retain moisture and soften skin. 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.
