What should I know about hautalterung?

Skin aging (hautalterung) is influenced by both genetics and environment, but the provided context lacks direct evidence on this topic. While some genes (e.g., those involved in collagen production, antioxidant defense, or telomere maintenance) have been linked to skin aging in mechanistic or observational studies, the effect sizes are small and not clinically actionable for most individuals. Consumer DNA tests often claim to predict skin aging, but these claims are typically based on weak or unreplicated associations. The strongest evidence supports lifestyle interventions: sun protection (UVA/UVB), a diet rich in antioxidants and omega-3s, adequate hydration, and avoidance of smoking and excessive alcohol. No single gene variant determines your skin's fate. Evidence: unclear (no direct context). Sources: none from provided context.
