Dermatitis is a general term for skin inflammation that can cause redness, itching, dryness, scaling, irritation, or a rash. It is not a single skin condition. Different forms of dermatitis have different causes and triggers, which is why identifying the type of dermatitis is an important first step toward effective treatment.
At OC MedDerm in Irvine, dermatitis is evaluated based on your symptoms, medical history, skin examination, and potential triggers. Patients from Irvine and throughout Orange County can receive a personalized treatment plan based on the specific type of dermatitis affecting their skin.
Dermatitis can develop for several different reasons. Common factors include:
The cause depends largely on the type of dermatitis. For example, atopic dermatitis is strongly associated with genetics and immune system dysfunction, while contact dermatitis develops after exposure to an irritant or allergen.
Atopic dermatitis, commonly called eczema, is a chronic inflammatory skin condition that can cause dry, itchy, irritated patches.
Flare-ups may be triggered by:
Contact dermatitis develops when the skin reacts to something it comes into contact with.
There are two main types:
Irritant contact dermatitis occurs when a substance directly damages or irritates the skin. Common examples include soaps, detergents, cleaning products, chemicals, and frequent water exposure.
Allergic contact dermatitis occurs when the immune system reacts to a specific substance. Potential allergens include fragrances, nickel, cosmetics, hair dyes, latex, and certain topical medications.
Seborrheic dermatitis commonly affects areas with a higher concentration of oil glands, including the scalp, face, and upper chest. It can cause redness, scaling, and flaking.
Common factors that may contribute to flare-ups include:
Other forms include stasis dermatitis, dyshidrotic eczema, nummular eczema, and asteatotic eczema. Each can have different contributing factors and triggers.
Even when dermatitis is under control, certain factors can cause symptoms to return.
Common triggers include:
Cold or dry air can remove moisture from the skin and worsen dryness and irritation.
Stress can contribute to flare-ups in some people with inflammatory skin conditions, including eczema and seborrheic dermatitis.
Fragrances, harsh cleansers, exfoliating products, and certain cosmetics may irritate sensitive skin.
Frequent washing or exposure to strong soaps and detergents can damage the skin barrier and contribute to irritation.
Heat and perspiration may worsen itching and irritation in some individuals.
If you have allergic contact dermatitis, exposure to a specific allergen can trigger a reaction. Identifying and avoiding the responsible substance can help prevent future flare-ups.
While not every flare-up can be prevented, several habits may help keep dermatitis under control:
If you are experiencing recurring rashes, identifying the specific type and trigger is important rather than simply treating the symptoms.
Consider seeing a dermatologist if your rash:
Because several skin conditions can look similar to dermatitis, a proper examination can help determine the underlying cause.
Treatment depends on the type and severity of dermatitis. Depending on your condition, your dermatologist may recommend moisturizers, topical medications, trigger avoidance, or other treatments.
At OC MedDerm in Irvine, Dr. Parvin Shafa evaluates inflammatory skin conditions and develops individualized treatment plans for patients in Irvine and throughout Orange County.
Most forms of dermatitis are not contagious and cannot be spread through skin-to-skin contact.
Stress does not necessarily cause dermatitis by itself, but it can contribute to flare-ups or make existing symptoms worse in some people.
Triggers vary depending on the type of dermatitis. Common triggers include dry skin, irritants, allergens, stress, heat, sweating, and environmental changes.
Some forms of dermatitis can be controlled for long periods, while chronic forms may periodically flare. Identifying triggers and following an appropriate treatment plan can help manage symptoms.
Not necessarily. Harsh or fragranced products may worsen irritation, but your dermatologist can recommend appropriate skincare products and treatments based on your specific condition.
Dermatitis can have many different causes, and identifying the specific type is essential for managing recurring flare-ups. Genetics, immune activity, irritants, allergens, environmental conditions, and lifestyle factors can all play a role.
