Citrus Limon (Lemon) Fruit Extract is derived from lemon fruit and contains citric acid, vitamin C, and flavonoids; it is used in skincare for its mild astringent, antioxidant, and brightening properties. It can act as a natural exfoliant and fragrance component.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation (stinging, redness) | Common | Citric acid and low pH can irritate sensitive or compromised skin. |
| Phototoxicity/photosensitivity | Uncommon | Citrus-derived furocoumarins (e.g., bergapten) may increase UV sensitivity, though fruit extract typically has lower levels than peel oils. |
| Allergic contact dermatitis | Uncommon | Limonene and other constituents are known fragrance allergens. |
| Dryness or barrier disruption | Uncommon | Acidic exfoliating action can compromise skin barrier with overuse. |
| Phytophotodermatitis (blistering hyperpigmentation) | Rare | Occurs with concentrated topical citrus plus strong sun exposure. |
