Myths vs facts: DNA Stoffwechselanalyse | inkl. 28-Tage-Plan & Rezeptbuch and fertility

Claims that a skin DNA test can reliably predict your risk of wrinkles or loss of elasticity are scientifically overstated. Genes like COL1A1 are indeed associated with collagen structure, but the evidence comes from GWAS studies with small effect sizes. This means the genetic contribution is real but minor. UV exposure, diet, sleep, and stress have a far greater impact on skin aging. Testing COL1A1 provides only a small piece of the puzzle, not a prediction. Furthermore, no validated genetic test for glycation susceptibility (AGEs) exists. Markers offered by MyBody-X (e.g., rs713598, rs10830963, rs4680) have only indirect, mechanistic links to skin glycation – no clinically confirmed predictive power. Bottom line: such tests can serve as lifestyle inspiration but not as medical diagnostics. To slow skin aging, focus on sun protection, antioxidants, and a healthy lifestyle – not on genetic tests.
