What role does Skincare DNA play in Langlebigkeit?

The role of 'Skincare DNA' in longevity is often marketed rather than evidence-based. Variants like GPX1 rs1050450 or IL-1B rs1143634 may influence skin inflammation and oxidative stress, but effects are small and mechanistic. No human study directly links a skincare DNA test to increased lifespan. Longevity is primarily driven by diet, exercise, sleep, and stress management. Consumer DNA tests are screening tools, not diagnostic. Evidence is mostly mechanistic or marketing. Be cautious: skin aging is multifactorial, and single SNPs explain minimal variance.
