Science
Mechanism of Action
It functions through a rich profile of terpenes (sabinene, pinene) and flavonoids that inhibit the growth of acne-causing bacteria like P. acnes and S. aureus. On a cellular level, it suppresses the NF-κB inflammatory pathway, reducing the production of pro-inflammatory cytokines while simultaneously stimulating collagen type I synthesis and providing antioxidant protection via ROS scavenging.

Key findings
- 01 In a double-blind trial, fermented Hinoki extract reduced inflammatory acne lesions by 65.3% over 8 weeks, notably outperforming tea tree oil (38.2%).
- 02 In vitro analysis demonstrated significant increases in collagen type I and superoxide dismutase (SOD) mRNA levels, supporting anti-aging and antioxidant defense.
- 03 Dermatological patch testing of formulations containing up to 90.6% concentration yielded a 0.00 irritation score.
