Dermatitis
Mild
Dermatitis refers to inflammation of the skin that commonly causes itching, redness, dryness, irritation, or a rash. Different types can develop because of allergens, irritants, genetic susceptibility, or immune reactions. Contact with substances such as soaps, detergents, chemicals, cosmetics, or metals may cause or worsen some forms, while other forms are associated with a weakened skin barrier.

When to Seek Medical Attention
Dermatitis is usually not an emergency, but persistent or worsening inflammation should be evaluated. Seek medical care for extensive or rapidly worsening redness, significant pain, blistering, fever, pus, or other signs of infection. Urgent evaluation is appropriate when symptoms spread rapidly or there is significant systemic illness.

Causes
Dermatitis can develop from allergens, irritants, genetic susceptibility, or immune reactions. Contact dermatitis may occur after exposure to substances such as soaps, detergents, chemicals, solvents, metals, cosmetics, or plants. Atopic dermatitis is associated with genetic and immune factors and a weakened skin barrier. Different forms of dermatitis can therefore have different underlying causes and triggers.
Risk Factors
Risk factors for dermatitis depend on the type. A personal or family history of allergies, asthma, or eczema can increase susceptibility to atopic dermatitis. Frequent exposure to soaps, detergents, chemicals, solvents, metals, cosmetics, plants, or other irritants can contribute to contact dermatitis. Dry skin, repeated hand washing, occupational exposure, and a weakened skin barrier may also increase risk.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis of dermatitis generally involves a detailed medical history and examination of the skin. A healthcare professional may ask about symptoms, timing, exposures, products used on the skin, occupation, allergies, and previous skin conditions. Allergy testing or patch testing may be considered when allergic contact dermatitis is suspected. A skin biopsy may occasionally be used when the diagnosis remains uncertain.
Prevention
Key Prevention Tips
Avoiding known skin irritants and allergens can help reduce dermatitis flare-ups
Use gentle skin-care products, avoid unnecessary exposure to harsh soaps and chemicals, and maintain adequate skin hydration to support the skin barrier
Protective measures may be useful when occupational exposure to irritants is unavoidable
Identifying and avoiding personal triggers can be particularly helpful for people with recurrent dermatitis
Prevention Guidance
Avoiding known skin irritants and allergens can help reduce dermatitis flare-ups. Use gentle skin-care products, avoid unnecessary exposure to harsh soaps and chemicals, and maintain adequate skin hydration to support the skin barrier. Protective measures may be useful when occupational exposure to irritants is unavoidable. Identifying and avoiding personal triggers can be particularly helpful for people with recurrent dermatitis.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
