CINNAMOMUM CAMPHORA FORMOSANA WOOD OIL.

This wood oil, specifically a linalool-rich chemotype of C. camphora, operates through several distinct pathways on the skin. It modulates inflammatory responses by controlling cytokine release and macrophage activity, notably reducing pro-inflammatory markers such as IL-1β, IL-6, and TNF-α. Its antimicrobial and antifungal actions are largely attributed to linalool, which demonstrates bactericidal efficacy against acne-related microorganisms like Staphylococcus aureus. The oil also stimulates cold-sensitive TRPM8 receptors on cutaneous nerve endings, inducing a cooling sensation and a mild anesthetic effect to alleviate irritation. Further benefits include an astringent action to refine pores, stimulation of skin microcirculation for enhanced cell renewal, regulation of sebum production, and antioxidant protection. It may also enhance the dermal penetration of other active ingredients.
