Skin-based interventions have a supportive but limited role in food allergy prevention. While moisturizers and skin cleansing alone are insufficient to prevent food allergy, early and adequate control of atopic dermatitis appears central to suppressing percutaneous sensitization. Effective prevention requires integrated, risk-stratified strategies combining optimal eczema management with appropriate food introduction and environmental considerations based on the dual allergy exposure theory. Further research is needed to establish well tolerated and sustainable prevention frameworks applicable to early life.
