Myths vs facts: IgG and skin aging

The claim that IgG food sensitivity tests can address skin aging is a myth not supported by scientific evidence. IgG antibodies to foods are often a normal immune response and do not reliably indicate intolerance or allergy. Studies show IgG tests have high false-positive rates and lack clinical validation for skin conditions or aging. Skin aging is primarily driven by oxidative stress, glycation, UV damage, collagen degradation, and genetics. Eliminating foods based on IgG results may lead to unnecessary restrictions and nutrient deficiencies. MyBody-X itself refutes unproven IgG panels. Evidence-based strategies for skin health include a balanced diet rich in antioxidants, sun protection, and proper skincare. Consult a dermatologist or registered dietitian for personalized advice.
