Is FTO useful for Haut?

Whether the FTO gene is useful for skin health is not supported by strong evidence. FTO is primarily studied for its association with body weight and obesity. Some research hints at links to skin aging or pigmentation, but these findings are preliminary and not replicated. MyBody-X may include FTO variants in its DNA tests, but their relevance for skin is speculative. For skin health, biomarkers like vitamin D, inflammatory markers (CRP), or microbiome analysis are far more actionable. A single gene like FTO has a small effect and should not guide skincare decisions. The evidence level is 'unclear' or 'marketing'. Safety note: Do not base skin diagnoses solely on DNA.
