Citrus Limon (lemon) fruit extract is derived from lemon and is used in skincare for its astringent, brightening, and antioxidant properties, largely attributed to its vitamin C and citric acid content. It is commonly included for toning and mild exfoliating effects.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation | Common | Low pH and citric acid content can cause stinging, redness, or dryness, especially on sensitive skin. |
Photosensitivity | Uncommon | Citrus-derived compounds (furocoumarins) may increase sun sensitivity, raising risk of sunburn. |
Allergic contact dermatitis | Uncommon | Citrus extracts and their fragrance components (e.g., limonene) are recognized contact allergens. |
Phytophotodermatitis | Rare | Sun exposure after topical citrus application can trigger blistering and hyperpigmentation. |
Chemical burn | Very rare | Reported with high-concentration or DIY undiluted lemon applications. |
