What does Coenzyme Q10 do in a cream, and why is it considered useful for skin that looks tired or is exposed to pollution?

Coenzyme Q10 is a substance naturally present in your skin, involved in cellular energy production. In cosmetic formulas like this one, its primary role is as an antioxidant. This means it helps limit the impact of oxidative stress caused by environmental exposure, including UV light and pollution particles from city air. When skin is constantly exposed to these factors, or as it matures, its own natural Q10 levels can decline. Applying it topically is a common way to provide the skin with additional antioxidant support. The idea is not to treat a condition but to help the skin maintain a smoother, more rested appearance by supporting its defence against daily environmental stressors. It is widely used in anti-ageing and protective cosmetics for this purpose. It works alongside other ingredients like Allantoin here, which focuses on softening the skin and reducing feelings of roughness.
