Cow’s milk allergy is the single most common food allergy in children; it manifests with eczema, urticaria, gastrointestinal symptoms, respiratory symptoms, or anaphylaxis.1 Current management relies on avoidance and treatment of allergic reactions. Most reactions occur after milk ingestion; however, cutaneous exposure can also elicit symptoms. Pediatricians should be aware that children who are allergic to milk need protection not only from accidental ingestion of milk but also from topical exposures. Skin care and cosmetic products represent a clinically significant source of food allergens. We report 2 children with milk allergies who developed allergic reactions caused by cosmetic products containing milk proteins.
