Eucalyptus Globulus Leaf Oil
Ingredient Info
Eucalyptus Globulus Leaf Oil is a volatile essential oil extracted from eucalyptus leaves. It's used in skincare for its aromatic and potentially soothing properties, though it's typically found in small concentrations in topical formulations.
Benefits
- May provide a cooling or refreshing sensation
- Traditionally used for its antimicrobial properties
- Can add pleasant fragrance to products
Potential concerns
- High concentrations can reduce cell viability and irritate sensitive skin
- May cause irritation in individuals with sensitive or compromised skin barriers
- Volatile oils can be irritating if used undiluted or in excessive amounts
- Not recommended for use near eyes or on broken skin
Science: Research on human nasal epithelial cells shows that eucalyptus oil reduces cell metabolic activity in a dose-dependent manner, with a measured IC₅₀ of 31.55 µL. While the effect is gradual rather than immediately cytotoxic, this suggests the ingredient requires careful formulation and concentration control in skincare products to avoid irritation. More clinical data on topical skincare applications is needed.
