What is Contact Dermatitis? Posted on December 23, 2021 by Arizona Desert Ear, Nose & Throat Specialists If you’ve ever gotten a rash after accidentally touching poison ivy somewhere like the Sonoran Preserve, you’ve experienced contact dermatitis. Symptoms include: Itchy, discolored rash Dry, cracked and flaky skin Burning skin Blisters Swelling Feeling generally unwell Types of Contact Dermatitis There are three types of contact dermatitis. The symptoms are the same for each type. The difference is what causes the reaction. Irritant Contact Dermatitis Irritant contact dermatitis is the most common type of this condition, which accounts for 80% of all cases. Common causes include: Chemicals Friction Heat The rash will appear at the site of exposure. Its severity will depend on several different factors such as length of exposure, the strength of the irritant, as well as what part of the skin came into contact with the irritant. Allergic Contact Dermatitis This type of contact dermatitis occurs when your immune system produces an allergic response to a substance. People who regularly work with chemicals and other irritants like healthcare workers and hairstylists are more at risk for developing the condition. Some causes include: Poison ivy, oak or sumac Nickel or gold jewelry Substances in hair dye and cosmetics Rubber and latex Photocontact Dermatitis Sunlight is an essential part of photocontact dermatitis. It’s caused when a person comes into contact with an irritating substance and sunlight at the same time. Causes include: Lotions Shaving creams Certain medications Treatment and Prevention Tips Thankfully, most cases of contact dermatitis are relatively mild, and the reaction will go away shortly after exposure to the substance has ended. Topical anti-itch creams and antihistamines should help with any discomfort until the rash heals. Avoiding contact with known triggers is the best treatment and prevention for contact dermatitis. Occasionally, some people run into problems when they are unsure what is causing their reaction. If you regularly experience symptoms, but can’t pinpoint a trigger, make an appointment with an allergist. They can run allergy tests that will help you properly identify what is causing your contact dermatitis, so you know what to avoid.
