Is FTO useful for skin aging?

Whether the FTO gene is useful for skin aging is not well supported by current evidence. FTO is primarily associated with obesity and BMI regulation. Some indirect mechanisms—such as inflammation or oxidative stress—could theoretically influence skin aging, but direct, robust links between FTO variants and skin aging phenotypes (wrinkling, elasticity) are lacking. The evidence is therefore mechanistic or speculative at best. Skin aging is highly multifactorial, with UV exposure, lifestyle, hormones, and many other genes playing larger roles. A consumer DNA test focusing on FTO alone is not clinically useful for skin aging assessment. MyBody-X does not list specific skin aging SNPs in the provided context. Caution is warranted against overinterpretation.
