Science
Mechanism of Action
The extract functions through a multi-pathway approach: its citral and geraniol content modulates proinflammatory cytokines to reduce swelling, while its natural astringency physically tightens the follicular openings. Simultaneously, it acts as a purification agent, utilizing its antibacterial properties to disrupt the colonization of pathogens like Staphylococcus aureus and Pseudomonas aeruginosa on the skin surface.
Research
Clinical Evidence
Medium confidence5%
Key findings
- 01 At a 5% concentration, the essential oil demonstrated significant antibacterial efficacy against five major bacterial strains including S. aureus and P. aeruginosa.
- 02 Inhibitory effects were observed at concentrations as precise as 2.34 µg/ml for certain bacterial pathogens.
Transparency
Dusting Analysis
Because it often functions as a natural fragrance component, many formulations include it at levels below 0.1% for 'label appeal' rather than therapeutic astringency or antimicrobial benefit.
The Formula
Formulation
Stability
The hydrosol form is highly susceptible to oxidation; we recommend stabilized formulations or airtight, cool storage to maintain potency for up to 6 months.
Synergies
- Carrier oils for dilution
- Hydrating humectants to balance astringency
Conflicts
- Undiluted essential oil formats
- High-concentration allergens in reactive skin
Safety
Safety Profile
While generally low-risk, it contains natural fragrance compounds (citral, limonene, geraniol, farnesol) that are declarable allergens in the EU. ECHA data indicates potential for minor irritation.
