Science

Mechanism of Action

Fusanus Spicatus Wood Oil works by providing soothing, cooling, and moisturizing effects to the skin. It helps regulate sebum production without causing dryness or pore occlusion. Its antimicrobial action targets acne-causing bacteria, while its anti-inflammatory properties alleviate irritation linked to acne lesions and other mild inflammatory conditions. The oil has demonstrated a reduction in Matrix Metalloproteinase-1 (MMP-1), an enzyme associated with collagen degradation and photoaging. Furthermore, its key component, alpha-santalol, is a known tyrosinase inhibitor, suggesting a role in mitigating abnormal pigmentation. It also exhibits efficacy against various bacterial, fungal, and viral agents.
