Oxidative stress is one of the key factors that cause premature skin aging. It occurs when free radicals, such as reactive oxygen or nitrogen compounds, proliferate in the skin and natural protective mechanisms are no longer sufficient. Antioxidants can neutralize these molecules before they damage lipids, proteins, or the DNA of skin cells. In this way, antioxidants help maintain the skin's functionality.
Together, these antioxidants protect different structures in the skin, from membrane lipids to cell nuclei and mitochondrial energy reserves. This multi-layered approach helps the skin maintain its integrity against daily environmental stressors.
