Myths vs facts: NutriCare | INFINITY DNA-Test and skin aging

DNA tests like the NutriCare | INFINITY DNA-Test claim to personalize anti-aging skincare. Myth: A genetic test can precisely tell you how to stop skin aging. Fact: Skin aging is about 80 % determined by environmental factors (UV exposure, smoking, diet). Genetic variants (e.g., in collagen or antioxidant genes) have only small effects. Most direct-to-consumer tests rely on SNP associations from GWAS, which are often not validated in clinical trials. The recommendations (e.g., more vitamin C or sunscreen) are usually standard advice that applies regardless of genotype. Therefore, results are more entertaining than medically binding. To truly slow skin aging, rely on proven measures: daily sunscreen, no smoking, healthy diet, and adequate sleep. A DNA test may serve as extra motivation but does not replace medical consultation. Evidence: marketing/unclear.
