Science
Mechanism of Action
This extract exerts its effects through multiple pathways, primarily its rich content of flavonoids, terpenes, acetophenones, and phloroglucinols. It demonstrates anti-inflammatory action by inhibiting arachidonic acid metabolism and other pro-inflammatory mediators, soothing irritated skin. Its antimicrobial activity targets pathogens like Staphylococcus aureus. As an antioxidant, compounds like arzanol protect keratinocytes from apoptosis and preserve mitochondrial membranes, combating oxidative stress. Crucially, it promotes skin regeneration by significantly upregulating FGF-2 (1.74-fold change) and HAS-2 (3.10-fold change) gene expressions in human dermal fibroblast cells. These anabolic effects on the extracellular matrix are vital for re-epithelization, angiogenesis, granulation tissue formation, and hyaluronic acid synthesis, leading to improved wound healing, increased collagen production, and enhanced lipid barrier function. Additionally, its flavonoids contribute to anti-erythematous and photoprotective activities.

Key findings
- 01 Upregulation of FGF-2 (1.74-fold) and HAS-2 (3.10-fold) gene expressions in human dermal fibroblast cells, indicating anabolic effects on the extracellular matrix, promoting wound healing and UV protection.
- 02 Reduced local inflammation, edema, bruises, and hematomas in post-operative scars over 2-3 months.
- 03 Increased skin hydration and reduced trans-epidermal water loss (TEWL) in 25 participants over 30 days, without irritation or pH disruption.
- 04 Effective against Herpes Simplex Virus type 1 (HSV-1) activity.
- 05 Reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced chronic inflammation in mouse ear by 65%.

The Formula
Formulation
Conflicts
- Known allergens (e.g., limonene, eugenol, linalool) if the extract is not processed to reduce them; a boiling process can achieve a higher ratio of beneficial polyphenols/phenols to these allergens.
- Strong irritants or sensitizers, due to the potential for individual allergic reactions or irritation.
Safety
Safety Profile
Generally considered safe for topical use, though a patch test is recommended as some individuals may experience skin irritation or allergic reactions. One case of allergic reaction has been reported. The ingredient does not exhibit significant levels of cytotoxicity or genotoxicity. Avoid using on broken or damaged skin, and it is advised to avoid if pregnant or breastfeeding. European Union and other regulatory bodies recognize it as a safe cosmetic ingredient, but recommend following manufacturer's instructions.
