Detailed answer

Methylisothiazolinone (MI) is a common preservative used in many personal care products and household items. People with MI allergies can develop contact dermatitis, which is characterized by symptoms such as redness, itching, and inflammation. Eczema, also known as atopic dermatitis, is a chronic skin condition that causes dryness, itching, and a compromised skin barrier. MI allergies can trigger or worsen eczema symptoms, leading to flare-ups and increased skin sensitivity. It is important for individuals with eczema to avoid products containing MI and other potential irritants to manage their condition effectively.
