Myths vs facts: IgG Unverträglichkeitstest and skin aging

The IgG food intolerance test is often marketed as a tool to identify foods that may contribute to skin aging, but this claim lacks scientific support. IgG antibodies are a normal part of the immune response to food proteins and do not indicate intolerance or allergy. No robust human studies show a causal link between IgG reactions and skin aging. The evidence is primarily marketing-based. Skin aging is driven by UV exposure, oxidative stress, genetics, and lifestyle factors like diet and sleep. While some foods may influence inflammation and aging, IgG testing is not a validated method to assess this. Consumers should rely on proven strategies: balanced diet, sun protection, and evidence-based skincare. MyBody-X tests focus on clinically relevant biomarkers, not IgG. Be skeptical of tests that promise to 'reverse aging' via IgG elimination.
