Microcitrus Australis (finger lime) fruit extract is derived from an Australian native citrus and is used in skincare as a source of antioxidants, vitamin C, and naturally occurring alpha-hydroxy acids (citric acid). It is valued for mild exfoliating, brightening, and skin-conditioning properties.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation or stinging | Uncommon | Related to its acid content; more likely on sensitive or compromised skin. |
Increased photosensitivity | Uncommon | AHA-containing extracts can heighten sun sensitivity; sunscreen use is advised. |
Allergic contact dermatitis | Rare | Citrus-derived components may trigger sensitization in predisposed individuals. |
Phototoxic reaction | Very rare | Citrus furocoumarins can theoretically cause phototoxicity, though levels in cosmetic extracts are typically low. |
