What is Ubiquinone?

Ubiquinone is the cosmetic INCI name for coenzyme Q10, a fat-soluble, vitamin-like quinone compound produced naturally in human cells. It functions primarily in mitochondria to facilitate cellular energy production via the electron transport chain. Chemically, it exists in oxidized (ubiquinone) and reduced (ubiquinol) forms, with the former used in formulations. In skincare products, it belongs to the category of antioxidants and skin conditioning agents. Its lipophilic structure enables penetration into the stratum corneum, where it neutralizes free radicals generated by UV exposure and pollution. This stabilizes emulsions, prevents oxidation of other ingredients, and contributes to skin softness by emolliating the surface and enhancing barrier integrity. Typically sourced synthetically or via fermentation for purity, it integrates seamlessly into creams, serums, and oils targeting mature skin concerns.
