What are Skin Allergies?
Skin allergies are a kind of immune system reaction that occurs when your skin is exposed to a chemical that causes it to react in an allergic manner. A wide variety of allergens can cause skin allergies. This reaction may be minor or severe, ranging from itching and redness to hives and blisters as the most extreme manifestations. Some people are indeed more prone to developing skin allergies than others, but anyone at any age can develop an allergy.
