Types of Eczema

Atopic dermatitis is considered a more severe form of eczema, and it is very common. It is associated with elevated total immunoglobulin E (IgE) in serum, which means there are one or more triggers or allergens in presence. Atopic dermatitis starts in early childhood and is a chronic skin condition. Some grow out of it with time, while others carry it to adulthood. Atopic dermatitis is very itchy and appears commonly on the face, neck, arms, and legs. There is a hereditary factor, which means kids with parents who have atopic dermatitis have higher chances of getting atopic eczema themselves.

Contact dermatitis can be irritant-related or allergen-related.  An irritant is something that irritates or burns skin, such as certain chemicals, like strong bases or acids, sodium lauryl sulfate, or ingredients in poor quality skincare products, makeups, and soaps. Poison ivy or other poisonous plants may lead to severe reactions and itchy and painful blisters or rashes. Exposure to irritants will cause redness or itching, and prolonged exposure will lead to contact dermatitis. Nickel is not an irritant; however, it can also lead to an allergic skin reaction, so in this case, nickel is an allergen. Latex could also trigger an allergic reaction.

Seborrheic eczema is a common skin condition that causes redness, scaly patches, and in some cases, dandruff. It mostly affects the scalp, but it can also develop in oily areas, such as the face, upper chest, and back. When infants develop this condition, it is known as cradle cap. It typically develops within the first few weeks of life and gradually disappears over time. It may also occur in adults.
