Can DNA Stoffwechseltest help with Haut?

DNA metabolism tests (e.g., MyBody‑X) analyze genetic variants linked to skin aging, collagen breakdown, or inflammation – for example in the MMP gene (matrix metalloproteinases). However, the evidence is moderate: some GWAS and observational studies show small effects, but clinical predictive power is low. Skin health is far more influenced by UV exposure, diet, sleep, and lifestyle. Such tests are not medical diagnostic devices and are subject to Germany's Genetic Diagnostics Act (GenDG). Individual assessment by a dermatologist or nutritional physician is more appropriate. Antioxidants like vitamin E are safe up to 300 mg/day per EFSA (2024); high doses carry risks. Conclusion: The test may offer hints but does not replace professional advice. The evidence is insufficient for personalized skincare recommendations.
