The Coenzyme Q10, known in INCI as Ubiquinone, is a fat-soluble molecule found in the mitochondrial membranes of all cells, including skin cells. It belongs to the family of endogenous antioxidants: it is not a foreign active ingredient, but something the body already produces and has less of as the years go by.
It plays two roles. In the mitochondria, it takes part in the respiratory chain, the process by which cells obtain energy. As an antioxidant, it protects membrane lipids from oxidation caused by free radicals, and it is one of the very few compounds able to regenerate oxidized vitamin E, putting it back into circulation instead of leaving it depleted. This ability to reactivate another antioxidant is what makes it so valuable in an anti-aging formula.
It is recommended for mature skin and dull complexions, particularly for people with a history of extensive sun exposure. It is best used in the evening, when skin-repair processes are more active. Changes become visible after approximately eight weeks of consistent use.
It performs best alongside vitamin E, which it regenerates, and water-soluble antioxidants, which work in the aqueous phase where it cannot reach. This is why well-designed anti-aging formulas never contain it alone, but include it in a system where each antioxidant covers a different area.
