Science
Mechanism of Action
This extract operates through a synergy of active compounds, including citrus essential oils, flavonoids, and tannins. These constituents impart mild astringent properties, which assist in minimizing the visual appearance of pores and regulating excess sebum production, leading to a more toned complexion. Furthermore, flavonoids, alongside other secondary metabolites such as terpenoids and phenolics, contribute significant antioxidant activity, effectively neutralizing free radicals and bolstering the skin's natural defenses against environmental aggressors and signs of premature aging. It also provides a soothing and conditioning effect on the skin.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed Citrus Aurantifolia Flower Extract safe under current cosmetic practices, provided formulations are designed to be non-irritating and non-sensitizing. A critical consideration involves the potential presence of hydroperoxides of limonene and linalool, for which good manufacturing practices are advised to minimize impurities. While the U.S. FDA recognizes some citrus flowers as Generally Recognized As Safe (GRAS) for food applications, it is crucial to note that the related Citrus Aurantifolia Fruit Extract has been associated with increased skin sensitivity to sunlight and potential irritation. Consequently, individuals with sensitive skin should exercise caution or avoid this ingredient.
