Citrus Limon (lemon) extract is a plant-derived ingredient rich in vitamin C, citric acid, and flavonoids, used in skincare for its antioxidant, brightening, and mild astringent properties. It is also used as a fragrance and toning component in various formulations.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation/dryness | Common | Acidic and astringent nature can cause stinging, redness, or dryness, especially on sensitive skin. |
Allergic contact dermatitis | Uncommon | Citrus components and fragrance constituents (e.g., limonene, citral) are known sensitizers. |
Phototoxicity/photosensitivity | Uncommon | Furocoumarins in citrus can cause phytophotodermatitis with sun exposure, though expressed/processed extracts often have reduced levels. |
Hyperpigmentation | Rare | May follow phototoxic reactions, leaving post-inflammatory dark patches. |
Severe systemic allergic reaction | Very rare | Anaphylactic-type responses to citrus exposure are exceptional in topical use. |
