Lemon peel extract is derived from the rind of Citrus limon and is used in skincare for its antioxidant content (vitamin C, flavonoids) and mild brightening and astringent properties. It also imparts fragrance and may help even skin tone.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or stinging | Common | Citrus extracts can cause irritation, especially on sensitive or compromised skin. |
| Contact dermatitis (allergic or irritant) | Uncommon | Limonene and other citrus components are recognized allergens. |
| Phototoxicity/photosensitivity | Uncommon | Citrus peel may contain furocoumarins (psoralens) that increase sun sensitivity and can cause phytophotodermatitis. |
| Hyperpigmentation following sun exposure | Rare | Secondary to phototoxic reactions, particularly with concentrated or expressed citrus oils. |
| Severe allergic reaction | Very rare | Significant systemic or widespread hypersensitivity is uncommon. |
