What to watch with IgG Unverträglichkeitstest and skin aging?

The IgG food intolerance test measures antibodies indicating past exposure to foods, not true allergies or intolerances. There is no established scientific link between IgG test results and skin aging. Skin aging is primarily driven by UV exposure, genetics, lifestyle (smoking, diet), and collagen breakdown. While it is theoretically possible that inflammatory foods identified by an IgG test could contribute to systemic inflammation and thereby affect skin health, this remains speculative and unsupported by clinical evidence. The test is best used as a guide for elimination diets, not as an anti-aging tool. Caution: IgG tests should not replace medical evaluation for skin conditions or allergies. For slowing skin aging, proven strategies include sun protection, antioxidants (vitamin C, E), retinoids, and a balanced diet – not IgG-based dietary changes. The evidence for any benefit in skin aging is marketing-driven and unclear.
