Dermatitis
Dermatitis represents a broad category of skin conditions that can affect anyone at any age. It impacts the skin’s ability to hold moisture and protect against irritants, often resulting in discomfort and visible changes to the skin’s texture and appearance.
What Is Dermatitis?
Dermatitis is a general term describing skin inflammation characterized by itchiness, redness, and swollen skin.
Dermatitis serves as an umbrella term for several distinct conditions, including atopic dermatitis (eczema), contact dermatitis, and seborrheic dermatitis.
While the exact causes vary, most cases involve a mix of three things: a weak skin barrier, an overactive immune system, and environmental triggers. When your skin’s protective outer layer is damaged, irritants and everyday allergens can get in more easily. This leads to redness, swelling, and extra sensitive skin.
Expert Identification
At Core Dermatology, we see this condition frequently due to Denver’s unique arid climate. While the condition is common, effective treatment requires identifying the specific type of inflammation you are experiencing.
Common Symptoms of Dermatitis
Symptoms can vary depending on the type of dermatitis and the individual, but most cases share similar characteristics.
-
Persistent redness or swelling of the affected area
-
Intense itching (pruritus) that may worsen at night
-
Dry, cracked, or flaky skin
-
Blisters or oozing (in severe cases or infections)
-
Thickened or leathery skin patches from scratching
Local Tip: In Denver’s high altitude and dry air, symptoms often present with increased severity regarding cracking and dryness compared to humid climates.
The Three Main Types of Dermatitis
Because “dermatitis” is a broad term, identifying the specific sub-type is essential for proper treatment.
Atopic Dermatitis (Eczema)
Atopic dermatitis is a chronic inflammatory skin condition that often begins in childhood but may persist or start in adulthood. It is largely genetic and involves a malfunction in the immune system and the skin barrier leading to dry, itchy, and inflamed skin with increased sensitivity to environmental triggers.
Contact Dermatitis
This type occurs when the skin comes into direct contact with an irritant or allergen. It is categorized as either irritant contact dermatitis (caused by chemicals or friction) or allergic contact dermatitis (an immune reaction to a substance like nickel or poison ivy).
Seborrheic Dermatitis
This chronic form primarily affects areas of the body with many oil-producing (sebaceous) glands, such as the scalp, face, and upper chest. It causes red, flaky or greasy scales and is commonly associated with dandruff.
Common Causes and Triggers
Understanding the root cause of skin inflammation is vital for long-term relief. Causes are generally split into internal predispositions and external environmental factors.
Internal Factors
-
Genetics
A family history of eczema, asthma, or hay fever increases likelihood.
-
Immune System
An overactive immune system can cause the skin to flare up in response to minor triggers.
External Factors
-
Allergens
Pollen, pet dander, and dust mites.
-
Irritants
Harsh soaps, detergents, and certain fabrics.
-
Stress
High stress levels are a documented trigger for eczema flare-ups.
The “Colorado Factor”
In Denver, the environment acts as a significant agitator for dermatitis. The region’s notoriously low humidity constantly pulls moisture from the skin barrier, leaving it vulnerable to cracking. Additionally, high-altitude UV exposure and rapid seasonal temperature swings can further stress the skin barrier and trigger flares in sensitive individuals.
Dermatitis Treatment Options
Effective management often requires a combination of lifestyle changes and medical intervention.
Some things you can do at home to help manage symptoms are:
- Use fragrance-free thick moisturizers
- Take short lukewarm oatmeal baths
- Use a humidifier to reduce dryness
Medical Treatments
Dermatologists typically prescribe a regimen to reduce inflammation and repair the skin barrier. This often includes topical corticosteroids to calm flares quickly. For sensitive areas (like the face), calcineurin inhibitors are often used as a steroid-free alternative. In widespread cases, phototherapy (light therapy) uses controlled UV light to reduce inflammation.

Frequently Asked Questions (FAQ) About Dermatitis
Is dermatitis contagious?
No, dermatitis is not contagious. It cannot be spread from person to person through contact. It is caused by genetics, allergies, or environmental triggers.
Can the dry weather in Denver cause dermatitis?
Yes. Denver’s low humidity strips moisture from the skin barrier, making it more susceptible to inflammation, cracking, and eczema flare-ups.
When should I see a dermatologist for my rash?
You should see a provider at Core Dermatology if your rash is painful, infected, interferes with sleep, or does not respond to over-the-counter hydrocortisone within 1 week.
How can I tell which type of dermatitis I have?
The differences between types of dermatitis can be subtle, so diagnosis relies on a combination of history and physical examination. Your dermatologist will ask detailed questions about symptom onset, pattern, triggers, personal or family history of allergies, and recent product or environmental exposures (such as soaps, detergents, or plants like poison ivy). The location, appearance, and distribution of the rash also provide important clues, and in some cases, biopsy or other investigations may be used to confirm the diagnosis.
Is it possible I could be reacting to a product I’ve used for years?
Yes. While it is more common to develop a reaction to a product you’ve used several times, many people develop sensitivities to products they have used to years.
Is there a way to determine what I’m reacting to?
In addition to taking a detailed history and reviewing recent product or environmental exposures, your dermatologist may recommend patch testing to identify specific allergens. During patch testing, small amounts of common allergens are applied to your back under adhesive patches. The patches remain in place for 48 hours, and the skin is evaluated at 48 and 72–96 hours for any delayed allergic reactions. This test helps determine whether your dermatitis is caused by an allergic contact reaction and identifies the specific substances triggering it.
How long will my rash last?
The duration of a rash depends on its cause and how quickly triggers are addressed. For allergic or irritant contact dermatitis, the rash usually begins to improve once the offending substance is identified and avoided, though complete resolution may take several days to a few weeks. Topical corticosteroids or other anti-inflammatory treatments can help speed healing and reduce discomfort.
For allergic contact dermatitis, the allergy is typically lifelong, so avoiding the allergen is necessary to prevent recurrence. In contrast, atopic dermatitis (eczema) is a chronic, long-term condition. While flares can be managed and symptoms reduced with proper skin care and treatment, eczema is generally a lifelong issue with periods of remission and flare-ups.
