What role does NutriCare | INFINITY DNA-Test play in skin aging?

The NutriCare | INFINITY DNA Test claims to assess genetic predispositions for skin aging, including collagen metabolism, antioxidant defense, and glycation pathways. However, the scientific evidence is weak. While some GWAS have linked variants in genes like MC1R, COL1A1, or SOD2 to skin aging traits, effect sizes are small and not clinically actionable. Skin aging is predominantly driven by UV exposure, diet, smoking, sleep, and hormonal changes. No robust randomized controlled trial shows that acting on these genetic markers improves skin aging outcomes beyond standard skincare and lifestyle advice. Therefore, the test's role is primarily marketing: it may increase consumer engagement but lacks proven clinical utility. Consumers should be aware that direct-to-consumer DNA tests for skin aging are not diagnostic and should not replace dermatological evaluation. Evidence: marketing/unclear. Sources: none.
