Skin

Skin allergies (also called “allergic contact dermatitis”) occur when your skin comes in contact with an allergen that your skin is sensitive or allergic to. Also, allergies to other things like food you eat or proteins your breath in may cause symptoms to appear on your skin, such as hives or rashes. The reaction usually appears within 48 hours after the initial exposure to the allergen. Symptoms that are commonly seen include the following: redness, swelling, blistering, itching, hives and rashes. The allergen can be a substance in a product that you have used for many years; it does not have to be a new product. Allergic contact dermatitis occurs more commonly in adults. The most common types of allergic contact dermatitis are allergies to poison ivy, oak and sumac.
