Immunological Skin Reactions

Immunological skin reactions occur when the immune system responds to substances it mistakenly identifies as threats, such as allergens, pathogens, or irritants. This reaction can manifest as rashes, redness, itching, or swelling. Common examples include allergic reactions to plants like poison ivy, insect bites, or certain medications. Essentially, the body's defenses overreact, leading to inflammation and discomfort in the skin. Understanding these reactions helps in identifying triggers and managing symptoms effectively.
