Myths vs facts: DNA Stoffwechseltest and Haut

Myths vs. facts: DNA metabolism test and skin health. A DNA test can identify genetic variants related to nutrient metabolism (e.g., vitamins, fatty acids, collagen) that may influence skin elasticity or inflammation. However, the evidence for direct, personalized skin improvement solely from DNA-based dietary advice is weak. Many claims rely on GWAS with small effect sizes. The test can serve as a motivator for healthier eating but is not a substitute for dermatological evaluation. Myths include: 'the test tells me exactly which cream to use' or 'I can completely prevent skin aging.' These are not scientifically supported. Skin is heavily influenced by environmental factors (UV, skincare, lifestyle). A DNA test provides clues, not a diagnosis. Safety note: consult a doctor before taking high-dose supplements based on test results.
