Skin allergy is a change of the human skin which affects its color, appearance, or texture.
It may be localized in one part of the body, or affect all the skin. It may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell, and may be painful.
Allergies occur when your immune system reacts to a foreign substance. Your immune system produces proteins known as antibodies. These antibodies protect you from unwanted invaders that could make you sick or cause an infection. When you have allergies, your immune system makes antibodies that identify your particular allergen as something harmful, even though it isn't.
When you inhale the allergen or come into contact with it, your immune system responds and produces an inflammatory response on skin.
