What are Allergens and Irritants?

Allergens: Allergens are substances that can trigger allergic reactions in susceptible individuals. These reactions occur when the immune system mistakenly identifies the substance as harmful and produces an allergic response. Common allergens include pollen, dust mites, pet dander, mold spores, certain foods, and insect venom.

Irritants: Irritants are substances that can cause irritation or inflammation of the skin, eyes, nose, throat, or lungs, even in non-allergic individuals. Examples of irritants include cigarette smoke, air pollution, strong odors, and certain chemicals.
