An allergic rash is commonly characterized as skin irritation when allergens trigger the reaction by making the immune system to respond. When your skin is touched by an unfamiliar body, your immune system works in such a way that it sends an army of antibodies to wade off the intruder. As a result, a red itchy rash forms where the unfamiliar body had touched. Most people who have allergies often react to stuff that wouldn’t bother others.
Allergens can be characterized in three main forms; either by touch, through pollen, or airborne. The slightest touch from fragrances, plants, or dyes might cause an allergic rash reaction. Some people get allergy reaction rash when they are exposed to things in the air that settles on their skin such as pollen, chemical powders, spray, fibers, or smoke. Airborne contact allergies usually have an effect on your eyelids, head, and neck thus making it difficult for doctors to rule them out as an allergic reaction rash.
