Citrus Limon (Lemon) Extract is a plant-derived ingredient rich in vitamin C, citric acid, and flavonoids, used in skincare for its antioxidant, astringent, and skin-brightening properties. It is also added for fragrance and as a mild exfoliant via its natural acid content.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation/stinging | Common | Acidic components and essential oil residues can cause transient burning or redness, especially on sensitive or compromised skin. |
Phototoxicity/photosensitivity | Uncommon | Furocoumarins (e.g., bergapten) in citrus can trigger phytophotodermatitis with sun exposure, leading to burns or hyperpigmentation. |
Allergic contact dermatitis | Uncommon | Limonene and citral are recognized fragrance allergens that may sensitize susceptible individuals. |
Hyperpigmentation | Rare | Post-inflammatory or photo-induced darkening, particularly in darker skin tones after sun exposure. |
Severe blistering reaction | Very rare | Marked phytophotodermatitis with vesicles following high concentration exposure and intense sunlight. |
