According to Dr. Joshua Fox with Advanced Dermatology, contact dermatitis may seem perplexing because rashes can be triggered by an exhaustive list of substances.
Roslyn Heights, NY (PRWEB) May 20, 2014
Just as temperatures rise and you’re ready to don warm-weather clothes again, bam! You come down with a nasty red rash. But are you having an allergic reaction or is your skin just irritated? Contact dermatitis – which can be triggered by either allergens or skin irritants – is likely to blame, according to Joshua Fox, MD, medical director of Advanced Dermatology P.C.
Contact dermatitis is the medical name for rashes caused by culprits ranging from soaps, cosmetics, fragrances, jewelry or plants such as poison ivy or poison oak. Some jobs also expose us to substances that can cause contact dermatitis, Dr. Fox explains.
“The red, itchy rash of contact dermatitis isn’t contagious or life-threatening, but it sure can be uncomfortable and unslightly,” Dr. Fox says. “Many people get these sorts of rashes from time to time. It’s important to know that a variety of home treatments and medical approaches can be used to quickly and effectively tackle contact dermatitis.” It is also possible now, through new testing to find the etiology of what caused the contact dermatitis and how to safely avoid it in the future.
Contact dermatitis may seem perplexing because rashes can be triggered by an exhaustive list of substances. There are two main types of contact dermatitis, irritant dermatitis and allergen dermatitis. Irritant dermatitis, the most common type, can be caused by:
Allergic dermatitis, on the other hand, does not occur the first time you’re exposed to a substance – the reaction usually only happens after subsequent exposure. This form of contact dermatitis can be caused by:
Additionally, some products cause contact dermatitis only after the skin is also exposed to sunlight (photo contact dermatitis), including shaving lotions, sunscreens, coal tar products, some perfumes, and even oil from the skin of a lime.
“It’s not always easy to tell if your rash was caused by an allergy or by an irritant because some of the symptoms may be identical,” Dr. Fox explains. “But an allergy usually provokes symptoms on or near the skin you touched the allergen with, while a rash from skin irritants may be more widespread.”
“Also, with an allergy, it may be a day or two before the rash shows up,” he adds. “But with an irritant, the rash usually shows up immediately, and it tends to be more painful than itchy.”
Successfully treating contact dermatitis starts with identifying what’s causing your reaction. Avoiding the trigger usually gives the rash a chance to resolve on its own, though it may take two to four weeks. Home treatment measures, which can reduce inflammation and soothe skin, include:
If your rash doesn’t get better after a few days, it’s time to call your dermatologist, who may – for patients with long-term, repeated contact dermatitis – perform allergy testing with skin patches. So-called “patch testing” can determine which allergen is causing the reaction. We have hundreds of test so we can discover the correct allergens. The American Contact Dermatitis Association, of which I am a member, will tell us, through an agreement with multiple manufacturers, which products the patient should avoid as well as which products can be safely used with their specific allergy.
Clinicians may also prescribe heavy-strength ointments, creams or even pills to treat more severe cases of contact dermatitis.
“While sometimes treatment may be necessary, if it’s painful or uncomfortable and you are losing sleep or are distracted from your everyday life, it’s time to get your rash checked professionally. There’s no point in suffering in silence when treatment is so readily available. Failure to treat can lead to skin infection and scarring.”
