Detailed answer

Neomycin is an antibiotic that is commonly used in topical creams and ointments. However, some people can develop an allergic reaction to neomycin, leading to contact dermatitis or skin inflammation. Eczema is a chronic skin condition characterized by patches of dry, itchy, and inflamed skin. If a person with eczema develops an allergy to neomycin, it can aggravate their eczema symptoms, causing further inflammation, itching, and discomfort. Therefore, it is important for individuals with eczema to be mindful of any potential allergies to neomycin and avoid using products containing this ingredient.
