A wide range of causes might contribute to irritated skin. Immune system diseases, drugs, and infections are just a few examples of what you can experience. An allergic skin condition is one in which an allergen is the cause of the immune system's reaction. Typically harmless substances like wool, pollen, soap, or plants may cause a skin allergy. When this trigger is found, the immune system goes after it to get rid of it. The result is a rash on the skin that is red and itchy. Atopic dermatitis, contact dermatitis, and hives are all types of skin allergies.
An allergic skin response is itchy, red, or blistered skin. All the following symptoms may be present: itching, a raised bump, redness, or a combination of the three.
Symptoms and patterns may be used to identify different kinds of skin allergies. Over time, people's reactions might alter. A second exposure to the trigger may result in entirely different symptoms from the first.
