Anti-Aging | SKINCARE DNA-Test: which blood markers matter?

The question about an anti-aging skincare DNA test and relevant blood markers is valid, but the provided context does not describe such a specific test. Instead, it covers general DNA tests for nutrition/stress and the Nährstoff VitalCheck Basic blood panel, which includes vitamins (D, B12, folate), minerals (magnesium, zinc, selenium, iron, ferritin), and inflammatory markers. For skin aging, key blood markers include vitamin D (collagen synthesis), zinc (wound healing), ferritin (iron status, oxidative stress), and possibly hs-CRP (inflammation). A skincare DNA test might theoretically analyze genes like COL1A1, MMP1, or SOD2, but this is not confirmed in the context. The evidence is largely marketing-driven: many companies claim personalized anti-aging recommendations without clinically validated SNP panels. Blood markers provide actual measured values that reflect current status and are modifiable by lifestyle. Caveat: a DNA test alone cannot replace blood analysis; combining both may be useful but has limited evidence. For effective anti-aging, measured biomarkers (e.g., vitamin D, HbA1c, lipid profile) are more actionable than genetic risk scores.
