Citrus Grandis (grapefruit) Fruit Extract is derived from grapefruit and is used in skincare for its antioxidant, brightening, and skin-conditioning properties, owing to its content of vitamin C, flavonoids, and other phytochemicals. It is often included for its astringent and toning effects.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or stinging | Uncommon | More likely on sensitive or compromised skin, partly due to acidic pH and fragrance components. |
| Allergic contact dermatitis | Rare | Possible sensitization to citrus-derived constituents such as limonene. |
| Photosensitivity / phototoxicity | Rare | Citrus extracts may contain furocoumarins (psoralens) that can increase UV sensitivity, though fruit extracts generally contain less than peel oils. |
| Contact urticaria | Very rare | Immediate hives-type reaction reported with citrus exposure in predisposed individuals. |
