Science
Mechanism of Action
This oil, notably rich in alpha-santalol, functions as a potent anti-inflammatory agent by inhibiting 5-lipoxygenase and reducing interleukin 1b expression in keratinocytes, effectively calming redness and irritation. Its broad-spectrum antibacterial activity targets common skin pathogens such as Propionibacterium acnes, Staphylococcus epidermidis, and Streptococcus pyogenes. As an antioxidant, it neutralizes free radicals, mitigating oxidative stress and premature aging. The oil further supports skin health by acting as a natural emollient, stimulating collagen production for improved elasticity, and exhibiting astringent qualities that refine pores and enhance skin texture. Additionally, it aids in skin regeneration and reduces hyperpigmentation by inhibiting tyrosinase, the enzyme crucial for melanin synthesis.

Safety
Safety Profile
While specific CIR data for Santalum Austrocaledonicum Wood Oil is unavailable, related species like Australian sandalwood (Santalum spicatum) have been identified as potential contact allergens by the SCCS due to santalol content, indicating a risk of sensitization. General sandalwood oil may cause allergic skin reactions or irritation. Santalol itself was not irritating up to 20% in human studies but showed mild sensitizing potential in animal tests at 10%. Sandalwood album oil is recognized by the FDA as safe for flavoring at current usage levels. Essential oil precautions generally suggest a maximum concentration of 2% in topical formulations.
