Ceus Medica Limonum Fruit Extract is a citrus (lemon)-derived fruit extract used in skincare for its antioxidant, brightening, and mild astringent properties due to vitamin C, flavonoids, and citric acid content. It is sometimes included for toning and skin-refreshing effects.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or stinging | Uncommon | More likely on sensitive or compromised skin due to acidic pH and citrus compounds. |
| Photosensitivity | Uncommon | Citrus extracts may contain furocoumarins that can increase sun sensitivity, though levels in purified extracts are typically low. |
| Allergic contact dermatitis | Rare | Citrus limonene and related terpenes are recognized fragrance allergens. |
| Phytophotodermatitis (blistering/hyperpigmentation) | Very rare | Associated with high furocoumarin exposure combined with UV light. |
