Coenzyme Q10

Endogenous Antioxidant

Also known as: Ubiquinone, CoQ10, Ubidecarenone

Description

Coenzyme Q10 (ubiquinone) is a naturally occurring lipid-soluble benzoquinone that is present in virtually all human cells. It plays a dual role as an essential component of the mitochondrial electron transport chain and as a potent lipophilic antioxidant. Skin levels of CoQ10 decline significantly with age and UV exposure, making it a popular anti-aging ingredient. [Hoppe 1999]

Mechanism of Action

In its reduced form (ubiquinol), CoQ10 donates electrons to neutralize free radicals, protecting cell membranes and mitochondrial DNA from oxidative damage. It inhibits lipid peroxidation in the stratum corneum and dermis. CoQ10 also supports cellular energy production by shuttling electrons between Complex I/II and Complex III of the mitochondrial electron transport chain, fueling keratinocyte and fibroblast metabolism. It has been shown to reduce UV-induced MMP-1 expression, protecting collagen from photodegradation, and to reduce depth of wrinkles with regular use. [Hoppe 1999]
