Santalum Spicatum Seed Oil

Santalum spicatum seed oil is extracted from the seeds of Australian sandalwood. It's a plant-derived oil rich in fatty acids and phytosterols, which are compounds that help maintain skin's lipid barrier and moisture content.In skincare, it functions primarily as a skin conditioner—meaning it works to soften, smooth and hydrate the skin surface. Unlike heavier oils, it has a relatively light texture and absorbs reasonably well, making it suitable for layering into formulations without a heavy occlusive feel.

The oil's fatty acids penetrate the outer layers of skin, filling gaps between skin cells and reducing transepidermal water loss. This creates a softer, more supple appearance. The phytosterols present in the oil may also help reinforce the skin's natural lipid barrier, supporting its ability to retain moisture independently.Because it absorbs better than some heavier oils, it doesn't leave a prolonged greasy residue, which makes it easier to incorporate into daily routines without disrupting other steps.

Santalum spicatum seed oil works well in serums, facial oils, and moisturisers. It can be used daily as part of your routine, either as a standalone oil or blended into a cream. A little goes a long way—start with a few drops if using it neat, and adjust based on how your skin responds. It layers well with hydrating serums or water-based products applied beforehand.

Generally well-tolerated and suitable for most skin types. Patch test before widespread use if you have known sensitivities to botanical oils.
