Native to Southeast Asia, Calophyllum inophyllum, an evergreen-type tree, yields a large nut from which tamanu oil is obtained. The benefits of this oil (which is called sacred by native Tahitians) are plenty and the ingredient is often used in skincare products to ease inflammation, soothe sunburn and improve the skin's elasticity.
Due to its silky texture, tamanu oil soothes and softens, all while providing antioxidant, restorative and antibacterial properties, and that's exactly why this ingredient is included in blemish, acne, and wound-healing products. Bonus? With a rich nutty aroma, it smells great, too.
