Allergens can affect you in many ways, including through your skin. Allergic skin reactions aren't always easy to diagnose, especially if you don't also have traditional reactions such as breathing problems. You may even think that your skin problem is because of a product issue rather than a personal allergy. Here is more information about skin allergies and how to tell if you are having an allergic reaction.

What Are Common Skin Allergy Reactions?

Allergens cause the skin to react in several different ways. Below are the three most common ways for your skin to react if you are allergic to something.

Urticaria (Hives)

Hives are small, raised splotches or bumps that occur near the allergen contact point. These raised skin patches are often red and can be either small or large. Usually, they go away over time once the allergen is removed.


Dermatitis often covers irregularly-shaped scaly and red areas where the allergen makes contact. Often, these patches resemble eczema and are often itchy and flaky.


Angioedema is noticeable swelling after allergic contact. However, it doesn't necessarily cause redness or itching. You will mostly experience angioedema in your tongue, lips, or eyes if they make contact with the allergen.

What Are the Common Causes of Skin Reactions?

Not all allergens cause skin problems, but those that do are substances that have direct contact with the skin. Some of the most common substances that cause a skin reaction include:

  • Nickel
  • Perfume
  • Latex
  • Ultraviolet Light
  • Clothing (dyes or material)
  • Medications

Before stopping any medications, talk to your doctor and discuss your symptoms.

What Are Ways to Treat Skin Allergy Reactions?

If you can avoid the allergen, than that is all you may need to do to keep your skin healthy. However, if that is not always possible, then topical medications may help relieve the itching and swelling. Some of these medications, such as hydrocortisone and allergy creams, are available over the counter. Follow all directions carefully. If these medications don't work for you or are not strong enough, then talk to your doctor.

While not every rash is allergy-related, many allergens cause rashes and other skin problems. Repeated exposure may worsen these reactions over time. Knowing exactly what is causing your skin to react is helpful in avoiding additional or worsening reactions. Therefore, you should undergo allergen testing to find out what you are allergic to. Then, it's a matter of working with your doctor on the best way to prevent or alleviate your symptoms.
