There are seven types of the condition, and each has its own symptoms, prevention strategies, and treatment methods. Eczema is an inflammatory condition of the skin. While there are several different forms of eczema, all of them cause dry, flaky, scaly skin, redness, and itching. Atopic dermatitis is the most common form of eczema.
It typically begins during childhood. Atopic dermatitis often causes a red rash in the creases of the elbows and knees. Babies also often get atopic dermatitis on the scalp and cheeks. Atopic dermatitis is common among people with a personal or family history of hay fever or asthma as these conditions commonly occur together. Affected areas of the skin may turn darker and develop small bumps that can become infected if they're scratched and the skin is broken.
Atopic dermatitis is diagnosed by a dermatologist based on family history and the physical appearance of your skin. A skin biopsy may also help confirm diagnosis. Atopic dermatitis cannot be cured, but treatment can help decrease symptoms. This includes moisturizing the skin, managing stress, and avoiding triggers like irritating skin products, irritating clothing, extreme temperatures, and fragranced products. Topical treatment with steroids, crisaborole ointment, pimecrolimus cream, or coal tar can help reduce pain, redness, and itching.
For atopic dermatitis that does not respond to other treatments, phototherapy or biologics like Dupixent dupilumab may be recommended. Phototherapy involves exposing the affected skin areas to ultraviolet UV light two to three times a week to promote skin healing.
Dupilumab is a monoclonal antibody for the treatment of allergic diseases such as atopic dermatitis, asthma, and nasal polyps. It works to suppress the inflammation and help improve redness and itching. If you or your child has red, itchy patches of skin that have not gone away within a month, you should schedule a visit with your doctor to determine if you have atopic dermatitis and discuss appropriate treatment options.
Contact dermatitis occurs when your skin comes in contact with an irritating substance. The two forms of contact dermatitis are irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis occurs from direct skin exposure to an irritating chemical.
Allergic contact dermatitis occurs when your body initiates an immune system response and causes an allergic reaction in response to certain substances that come in contact with your skin. Urushiol, a substance naturally found in the sap and oils of Rhus plants such as poison ivy , poison oak, and poison sumac, is one of the most common causes of contact dermatitis.
It causes red streaks with raised bumps. Other common triggers include fragrances and metals like nickel found in jewelry and belt buckles.
Irritant contact dermatitis typically causes burning and pain at the exposed area. Itching is the main symptom of allergic contact dermatitis.
Irritant contact dermatitis will more commonly cause dry, cracked skin, while allergic contact dermatitis can form fluid-filled blisters. Contact dermatitis can be diagnosed by a primary care physician or dermatologist based on the physical appearance of your skin and reported symptoms. The best way to prevent irritant contact dermatitis is to:. If you suspect you may have an allergy to a certain substance, your doctor can perform skin patch testing , where patches that contain small amounts of common allergens are applied to the surface of your skin.
These patches are typically applied to your back or arm and left in place for 48 hours. During this time, you should avoid bathing, showering, swimming, and activities that cause a lot of sweating.
Irritated skin at the site of application may indicate an allergy to a particular substance that you should avoid contact with. Allergic contact dermatitis localized to a specific area can be treated with topical steroid creams such as triamcinolone 0. They can reduce pain and inflammation within 12 to 24 hours. Oral prednisone should generally be tapered off over the course of two to three weeks to prevent rebound dermatitis that can come back with sudden discontinuation of the medication.
Eczema is very common. In fact, more than 31 million Americans have some form of eczema. Eczema is not contagious. While the exact cause of eczema is unknown, researchers do know that people who develop eczema do so because of a combination of genes and environmental triggers.
Neurodermatitis is similar to atopic dermatitis. It causes thick, scaly patches to pop up on your skin. Neurodermatitis usually starts in people who have other types of eczema or psoriasis. This type of eczema causes round, coin-shaped spots to form on your skin. Nummular eczema looks very different from other types of eczema, and it can itch a lot. Nummular eczema can be triggered by a reaction to an insect bite, or by an allergic reaction to metals or chemicals.
Dry skin can also cause it. Stasis dermatitis happens when fluid leaks out of weakened veins into your skin. This fluid causes swelling, redness, itching, and pain. Stasis dermatitis happens in people who have blood flow problems in their lower legs.
If the valves that normally push blood up through your legs toward your heart malfunction, blood can pool in your legs. Your legs can swell up and varicose veins can form.
A skin doctor called a dermatologist can diagnose and treat eczema. To help your doctor understand your condition, it may be helpful to keep a diary to identify your eczema triggers.
Write down:. You should begin to notice connections between your activities and your eczema flare-ups. Bring this journal to your doctor to help them pinpoint your triggers. An allergy specialist can also do a patch test. This test places small amounts of irritating substances on patches that are applied to your skin.
The patches stay on your skin for 20 to 30 minutes to see if you have a reaction. This test can help your doctor tell which substances trigger your eczema, so you can avoid them.
Eczema often comes and goes.
