Our body activates our immune system to fight off foreign substances or substances it perceives as threatening. During this process, histamine and other chemicals are secreted in our body. These chemicals dilate blood vessels, causing symptoms such as redness and swelling on the skin. This condition is called allergy rash on the body.

Allergy rash occurs as a result of our body's defense mechanism overreacting. Our body perceives substances that are actually harmless as threats and begins to fight against these substances. This process leads to symptoms such as redness, itching and swelling on the skin.
