Science
Mechanism of Action
This essential oil penetrates deeply into the skin to exert potent anti-inflammatory and analgesic effects, effectively alleviating discomfort. It demonstrates significant antimicrobial, antibacterial, and antifungal capabilities, making it efficacious against a range of pathogens associated with conditions such as acne and various fungal infections. Furthermore, it possesses soothing and healing qualities that help to calm irritation, diminish redness, and accelerate the natural repair process of minor epidermal damage, including wounds and insect bites. Its antioxidant activity also contributes to overall skin health, and it has been traditionally used to aid in conditions like eczema and psoriasis.

Key findings
- 01 A 20% topical ointment formulation significantly improved healing for localized pastern dermatitis in horses, demonstrating its potent healing properties.
- 02 In a human clinical study for mild to moderate psoriasis using a 20% formulation, no statistically significant differences in clinical efficacy or pruritus scores were observed compared to an active control, although no adverse events were reported, suggesting good tolerability.
- 03 In-vitro studies revealed potent antimicrobial activity, inhibiting *P. aeruginosa* growth at concentrations as low as 33 µg/mL. Topical application also showed moderate antimicrobial effects against common hospital-acquired pathogens, including MRSA, other staphylococci, streptococcal spp., and Candida spp., with inhibition zones ranging from 9 to 18 mm.

The Formula
Formulation
Stability
To prevent auto-oxidation of alpha-pinene, a major component, it is critical to store the oil in a dark, airtight container under refrigeration (4°C) or freezing (-20°C). Oils stored in light at room temperature showed significantly higher color degradation (5.60 ± 0.03%) over eight months compared to samples kept in the dark.
Conflicts
- Oxidized essential oils can cause skin sensitization; proper storage is essential to prevent this degradation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not reviewed this ingredient. While generally well-tolerated for 'spot application' with minimal risk of irritation, information regarding safety during pregnancy and lactation is currently lacking. To mitigate the moderate risk of skin sensitization from oxidized oils, strict storage protocols are recommended: dark, airtight containers under refrigeration. It is certified suitable for cosmetic application and complies with EU regulations regarding prohibited substances, though it has not been reviewed by the FDA for safety or efficacy.
