Santalum Spicatum Sandalwood
What is Santalum Spicatum Sandalwood?
Santalum Spicatum Sandalwood is derived from the heartwood of the Santalum spicatum tree, native to Western Australia, and is valued for its aromatic essential oil and extracts used in skincare. It contains unique sesquiterpenes like α-santalol and β-santalol, which contribute to its anti-inflammatory, antimicrobial, and antioxidant properties. In cosmetics, it is typically incorporated as an oil or extract to soothe irritated skin and promote a calming effect.
