Citrus Limon (Lemon) Peel Extract is a plant-derived ingredient rich in flavonoids, vitamin C, and citric acid, used in skincare for its antioxidant, brightening, and mild astringent properties. It is often included for toning and as a natural fragrance or freshening agent.
| Reported effect | How often | Notes |
|---|---|---|
Skin irritation (redness, stinging, burning) | Common | Acidic and limonene content can irritate sensitive or compromised skin. |
Allergic contact dermatitis | Uncommon | Limonene and other citrus constituents are known sensitizers, especially when oxidized. |
Phototoxicity/photosensitivity | Uncommon | Citrus peel may contain furocoumarins (e.g., bergapten) that can increase sun sensitivity and cause phytophotodermatitis. |
Hyperpigmentation following sun exposure | Rare | Secondary to phototoxic reactions, particularly with leave-on products. |
Severe blistering reactions | Very rare | Reported with high concentrations and significant UV exposure. |
