Can Selen help with skin aging?

Selenium is an essential trace element with antioxidant properties that could theoretically help reduce oxidative stress in the skin, a key driver of skin aging. Some observational studies suggest a link between low selenium status and increased skin aging, and selenium is often marketed in supplements for skin health. However, clinical evidence for a direct anti-aging effect in humans is limited and conflicting. Excessive selenium intake is toxic (selenosis) and may even harm the skin. The effect depends heavily on individual baseline levels, genetic factors (e.g., MTHFR variants affecting folate/methylation metabolism), and overall diet. Single interpretations from genetic tests should be treated with caution. Selenium alone is not a miracle cure for skin aging; a balanced diet rich in antioxidants, sun protection, and proper skincare remain more important based on current evidence.
