Orange peel extract (Citrus sinensis/aurantium peel) is derived from citrus rind and supplies flavonoids, vitamin C, and aromatic essential oils used for antioxidant and brightening claims as well as natural fragrancing. It is commonly included in toners, masks, and brightening formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation (stinging, redness) | Common | Related to essential oil and limonene content, especially in sensitive skin. |
| Allergic contact dermatitis | Uncommon | Limonene and linalool oxidation products are known sensitizers. |
| Phototoxicity / photosensitivity | Uncommon | Citrus-derived furocoumarins may increase sun sensitivity, though peel extracts are usually lower in these than cold-pressed oils. |
| Worsening of eczema or rosacea flares | Rare | Fragrant citrus components can aggravate reactive skin conditions. |
| Severe blistering or burns | Very rare | Reported mainly with high-concentration or undiluted citrus oils plus UV exposure. |
