Antioxidant Skin Conditioning Antimicrobial Astringent Masking

The oil utilizes a complex of apiol, myristicin, and pinene to neutralize oxidative stress through DPPH radical scavenging. Its antimicrobial action occurs by destabilizing the phospholipid bilayers of harmful microorganisms, while its natural astringent properties help refine pore texture and firm skin tissue.
