Perfuming Antibacterial Antifungal Antioxidant Anti-inflammatory Astringent Dandruff Treatment

Science

This botanical oil exerts its effects through several mechanisms: its lipophilic compounds disrupt bacterial and fungal cell membranes, leading to antimicrobial action against common skin pathogens including those linked to acne. It also functions as a potent antioxidant, neutralizing free radicals that contribute to skin damage. Additionally, terpene fractions within the oil modulate local immune responses, providing anti-inflammatory benefits and supporting skin barrier repair. Astringent and healing properties further assist in refining skin appearance and diminishing blemishes.
