Citrus paradisi (Grapefruit) Fruit Extract is a botanical derived from grapefruit, valued for its vitamin C, flavonoid, and natural acid content, contributing antioxidant and mild astringent or brightening effects in skincare. It is commonly used as a conditioning and fragrance-contributing additive in cosmetic formulations.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or stinging | Uncommon | May occur on sensitive or compromised skin due to natural acids and citrus components. |
| Allergic contact dermatitis | Uncommon | Citrus extracts and associated fragrance constituents can act as sensitizers in predisposed individuals. |
| Phototoxicity / photosensitivity | Rare | Citrus-derived furocoumarins may increase sun sensitivity, though fruit extracts typically contain lower levels than peel oils. |
| Redness or contact urticaria | Rare | Immediate hypersensitivity reactions have been reported with citrus-derived ingredients. |
