Citrus Paradisi (grapefruit) Fruit Extract is derived from grapefruit and is used in cosmetics for its antioxidant vitamin C content, fragrance, and mild astringent/skin-conditioning properties. It is generally considered a supportive ingredient rather than a primary clinical active.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation or stinging | Uncommon | May occur on sensitive or compromised skin due to acidic pH and fragrance components. |
| Allergic contact dermatitis | Rare | Linked to limonene and other citrus terpenes that can oxidize and become sensitizing. |
| Phototoxic reaction (photosensitivity) | Rare | Citrus-derived furocoumarins may increase sensitivity to UV light, though processed fruit extracts typically contain low levels. |
| Contact urticaria | Very rare | Immediate hives reported in individuals with citrus allergy. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
