Grapefruit (Citrus paradisi) extract is a botanical rich in vitamin C, flavonoids, and naringin, used in skincare for its antioxidant and skin-brightening properties. It is also valued as a natural fragrance component and mild astringent.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation (redness, stinging) | Uncommon | More likely on sensitive or compromised skin, partly due to acidic pH and limonene content. |
| Allergic contact dermatitis | Uncommon | Linked to fragrance allergens such as limonene and other terpenes present in citrus extracts. |
| Phototoxicity/photosensitivity | Rare | Citrus extracts may contain furocoumarins (e.g., bergapten); risk depends on extraction and concentration, with sun exposure increasing reaction potential. |
| Pigmentation changes (phytophotodermatitis) | Very rare | Reported with concentrated citrus oils and sun exposure rather than typical low-concentration extracts. |
