Nonspecific dermatitis causes raised red bumps on the skin for no known reason. It is easily treated with OTC or prescription creams and you can reduce your risk by using moisturizers.
What is nonspecific dermatitis?
Dermatitis is inflammation of the skin that causes red areas of skin, raised red lumps, or blisters. There are different types and causes of dermatitis, but nonspecific dermatitis means there is no known cause for your dermatitis. About 50% of dermatitis cases are considered nonspecific.
Other types of dermatitis include allergic contact dermatitis (caused by contact with an allergen like poison ivy) and irritant dermatitis (caused by contact with something that irritates the skin like a detergent). Atopic dermatitis is a chronic skin condition, which tends to be genetic.
Whatever the cause, dermatitis is often treated similarly with moisturizers, gentle skin care, and OTC or prescription steroid creams.
Symptoms
Dermatitis is a red rash with lumps that most commonly occurs on the stomach, back, arms, and legs.
- Red skin
- Raised red lumps
- Rash may appear purple in brown or black skin
- Blisters may develop that become patches of bumps.
- If dermatitis lasts a long time, skin can become dry, thick, and scaly.
Pro Tip
People often think that dermatitis is caused by food. In adults, it is very rare that a food allergy is causing dermatitis. —Dr. Lauren Levy
Causes
The cause of nonspecific dermatitis is unknown. A dermatologist will ask you some questions and may run tests (like a skin biopsy or patch testing) to try to find a cause. But in many cases, no cause will be found.
Nonspecific dermatitis becomes more common with age because skin becomes more sensitive. Also, your skin barrier becomes less effective at keeping moisture in, which leads to dry skin that’s more prone to dermatitis.

Treatment will require some “work” for a few weeks to get your skin better. This means using either the OTC or prescription steroid twice a day for 2–3 weeks. It takes time for the rash to go away. —Dr. Levy
Treatment
Pro Tip
There are lots of newer medications on the horizon for those with dermatitis. If your non-specific dermatitis lasts for longer than a few weeks or months, you may be a candidate for an oral or injectable medication that can diminish your dermatitis and also treat itch. —Dr. Levy
You can treat most kinds of dermatitis with OTC or prescription creams.
- Hydrocortisone cream can relieve redness and itching.
- Try to improve the normal skin barrier and add moisture to your skin. Heavy-duty moisturizers (CeraVe, Cetaphil) are water-based and add moisture to skin. Emollients like petroleum jelly are oil-based and soften skin to help it stay moist and hydrated.
- Oral antihistamine can relieve the itching but may make you drowsy.
- Try to identify and avoid any substances that may be causing the irritation.
Preventative tips
- Take short showers rather than long showers or baths and avoid very hot water.
- Use soaps with a high fat or glycerin content.
- Avoid products with perfumes and dyes that may cause a sensitivity reaction. Look for fragrance-free products.
