- Squalane (Perhydrosqualene or perhydrosqualene vegetal): A signature Kiehl’s ingredient, Squalane is a botanical lipid that is similar in molecular structure to natural skin lipids. It has an exceptional affinity to skin, and because it’s easily absorbed, Squalane helps restore skin’s natural moisture balance to keep it extra soft and supple.
- Aloe Vera: Widely used for centuries in traditional and herbal medicine, Aloe is known to hydrate and soothe skin. Kiehl's Aloe is sourced from the leaf of the Aloe Vera plant growing in the Dominican Republic.
- Vitamin E: Naturally occurring in plant leaves and skin, Vitamin E helps neutralize skin-damaging free radicals and has soothing moisturizing properties.
