Citrus Aurantifolia (lime) Fruit Extract is derived from lime fruit and is used in skincare for its astringent, antioxidant, and skin-conditioning properties, often contributing vitamin C and natural acids. It is valued for toning and brightening effects but contains compounds that can increase sensitivity to light.
| Reported effect | How often | Notes |
|---|---|---|
| Phototoxicity / phytophotodermatitis | Uncommon | Furocoumarins (e.g., bergapten) in citrus can cause burning, redness, and hyperpigmentation upon sun exposure, especially with expressed oils. |
| Skin irritation | Uncommon | Natural acids and limonene may cause stinging or redness, particularly on sensitive or compromised skin. |
| Allergic contact dermatitis | Rare | Sensitization can occur, often linked to limonene and oxidized terpene constituents. |
| Post-inflammatory hyperpigmentation | Rare | Secondary to phototoxic reactions in sun-exposed areas. |
