Myths vs facts: Cardio Risk Check | Herz-Kreislauf Risiko-Test and Haut

The claim that a DNA or lab test for cardiovascular risk can also provide reliable insights into skin health is a myth. While certain genetic variants (e.g., FADS, APOA5) influence lipid metabolism and may indirectly affect skin – for instance through omega-3 levels or triglycerides – the effect sizes are small and the evidence is mostly observational (GWAS, mechanistic data). No randomized controlled trials demonstrate that dietary changes based on these variants improve both heart and skin outcomes. Hormone tests (cortisol, testosterone) have limited utility in healthy individuals without symptoms and are not validated for combined risk assessment. Fact: traditional risk factors such as LDL cholesterol, blood pressure, smoking, and physical activity are far more robust for cardiovascular prevention than any genetic 'skin-heart link'. Skin signs like xanthelasmas can indicate lipid disorders but require clinical evaluation, not a genetic test. Consumers should be wary of marketing claims that a single test can predict both cardiac and dermatological risks.
