In our reference data, Eucalyptus Globulus Leaf Oil can feed Malassezia (fungal acne).
Eucalyptus Globulus Leaf Oil is a volatile essential oil derived from eucalyptus leaves, rich in 1,8-cineole (eucalyptol), used in skincare for its aromatic, antimicrobial, and mildly soothing properties. It is most often added for scent or minor antiseptic effect rather than as a primary therapeutic active.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Common | Can cause stinging, redness, or irritation, especially on sensitive or compromised skin or at higher concentrations. |
Allergic contact dermatitis | Uncommon | Sensitization to eucalyptol and other terpene constituents can produce delayed allergic reactions. |
Photosensitivity/oxidation reactions | Rare | Oxidized terpenes may increase irritant or sensitizing potential over time. |
Systemic toxicity from ingestion or excessive exposure | Very rare | Reported with oral ingestion rather than topical cosmetic use; not typical from formulated skincare. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
