Can IgG Unverträglichkeitstest help with Haut?

IgG food intolerance tests are often marketed for skin issues like acne, eczema, or rosacea. However, scientific evidence is weak: IgG antibodies indicate immune exposure, not necessarily intolerance or allergy. Studies show no reliable benefit for diagnosing or treating skin conditions. Major medical organizations (e.g., EAACI, AAAAI) advise against these tests, as they frequently lead to unnecessary dietary restrictions without proven clinical utility. For genuine skin problems, consult a dermatologist or allergist for validated tests like specific IgE or patch testing. The evidence is largely marketing-based; anecdotal success stories are not generalizable.
