Dermatitis is a common skin condition that affects many people throughout their lives. It is a non-contagious inflammation of the skin that can cause itching, redness, and swelling.

There are several types of dermatitis that have different causes and symptoms. In this visual guide, we will explore the different types of dermatitis and how they can be treated.

Atopic Dermatitis

Atopic dermatitis, also known as eczema, is a chronic skin condition that often starts in childhood. It causes patches of dry, itchy skin that can be red and swollen.

The patches can appear anywhere on the body, but are most commonly found on the hands, feet, and face. Symptoms can be triggered by certain foods, allergens, or stress. Treatment options include moisturizers, topical corticosteroids, and immunosuppressants.

Contact Dermatitis

Contact dermatitis is a type of dermatitis that occurs when the skin comes into contact with an irritant or allergen. The skin can become red, itchy, and swollen and may even develop blisters.

The most common irritants are chemicals, soaps, and detergents. The most common allergens are plants, metals, and cosmetics. Treatment includes avoiding the irritant, applying topical corticosteroids, and taking antihistamines to relieve itching.

Seborrheic Dermatitis

Seborrheic dermatitis is a chronic skin condition that causes scaly patches and red skin, usually on the scalp, face, or chest. It is caused by an overgrowth of yeast on the skin. Symptoms can be triggered by stress, cold weather, and oily skin.

Treatment includes using medicated shampoos, antifungal creams, and topical corticosteroids.
