This oil is extracted from the seeds of the tamanu nut tree, a tropical plant native to Southeast Asia and Polynesia. Tamanu oil has a dark green color, is thick in consistency, and has a high content of fatty acids like linoleic acid, which helps to moisturize the skin. Used medicinally by many Asian and Pacific Island cultures, the oil also contains anti-inflammatory properties and helps promote wound healing. When combined with other active skincare ingredients, the oil helps reduce the likelihood of a sensitive reaction to the product.
