FTO is primarily associated with obesity and BMI through large GWAS. A higher BMI can accelerate skin aging via inflammation, oxidative stress, and altered collagen homeostasis. However, no robust studies demonstrate a direct causal effect of FTO SNPs on wrinkle formation, elasticity, or glycation. Mechanistic research suggests FTO influences adipose tissue function and adipokine secretion, which may indirectly affect skin. Thus, the evidence is GWAS-based (for BMI) and mechanistic (for skin), not clinically validated. A consumer DNA test like MyBody-X can detect FTO variants, but its predictive value for skin aging is low. Other factors—UV exposure, diet, hormones, lifestyle—dominate. Consumers should not take targeted anti-aging actions based solely on FTO genotype. Instead, proven strategies (sunscreen, antioxidants, healthy diet) should be prioritized.
