Myths vs facts: FTO and skin aging

Claims linking FTO directly to skin aging are not supported by strong evidence. FTO (Fat Mass and Obesity Associated) is primarily associated with body weight, obesity risk, and appetite regulation – not skin aging. GWAS show small effect sizes on BMI, but no robust link to wrinkle formation or skin elasticity. Skin aging is driven by UV exposure, lifestyle (smoking, diet), and other genes (e.g., MC1R, collagen-related). Some companies market FTO tests as 'skin aging risk', but the evidence is weak. MyBody-X analyzes antioxidant capacity (SOD2, GPX) and skin health, but not FTO-related aging. Bottom line: FTO is not a meaningful marker for skin aging. Focus on sun protection, antioxidants, and healthy habits. Evidence: mixed (no direct study base).
