Antioxidant

Ubiquinone

Coenzyme Q10 is a natural antioxidant produced in every cell of the body. With age, its level decreases, accelerating cellular aging. In cosmetics, it protects the skin from free radicals and supports the cellular energy of mitochondria.

What is it?

Ubiquinone (CoQ10) — 2,3-dimethoxy-5-methyl-6-decaprenyl-1,4-benzoquinone. Molecular weight ~863 Da. Fat-soluble. Bright yellow or orange powder. Reduced form: Ubiquinol (QH2) — an even more active antioxidant. Biosynthesized in the body from mevalonate (the same pathway as cholesterol). The level decreases from age 30: the skin of a 20-year-old contains ~1 mg/g CoQ10, while that of a 50-year-old contains ~0.3 mg/g. Concentrates in mitochondria: plays a key role in ATP synthesis (cellular energy). Cosmetic concentrations: 0.1–1%. Poorly penetrates the stratum corneum due to high MW (~863 Da) → applying CoQ10 in liposomes or nanoemulsions increases effectiveness.

Anti-aging creams and serums (30+), products for mature skin, eye creams (the skin around the eyes loses CoQ10 the fastest), products for protection against photoaging.

Key Benefits

✦

Mitochondrial protection — cellular energy for youthful skin

CoQ10 is essential in the mitochondrial respiratory chain: it transfers electrons between complexes I, II, and III → ATP synthesis. Skin with sufficient levels of CoQ10 synthesizes collagen "more efficiently," regenerates after damage, and maintains barrier function. Clinical studies by Beiersdorf (Nivea) in 1998 were the first to prove the effectiveness of topical CoQ10: a 27% reduction in wrinkle depth after 6 months.

◈

Antioxidant protection from UV and free radicals

Ubiquinone neutralizes free radicals directly in the mitochondria — the first line of defense against oxidative stress. When exposed to UV: it neutralizes ROS (reactive oxygen species) generated in the skin's mitochondria. Synergy with vitamin E: CoQ10 regenerates oxidized vitamin E → both antioxidants retain activity longer. Protects DNA from UV-induced mutations.

✧

Stimulation of collagen and elastin synthesis

Studies show: regular application of CoQ10 stimulates the synthesis of collagen types I and III by fibroblasts. Mechanism: the reduced form (ubiquinol) activates signaling cascades related to TGF-β and fibroblast proliferation. Result — increased skin firmness and density with prolonged use (8–12 weeks). The most pronounced effect occurs with the combination of CoQ10 + vitamin C + niacinamide.

Ubiquinone vs Ubiquinol — which form is better?

Ubiquinone (oxidized form, CoQ10): more stable in the formula, requires reduction in the skin to ubiquinol for maximum activity. Ubiquinol (reduced form): directly active antioxidant, but less stable in air and in the formula. For most products: ubiquinone is a reliable choice — stable, available, well-studied. Ubiquinol — in premium anaerobic packaging (airless pumps). The difference in effectiveness for topical application: minimal with proper formulation.
