Atopic dermatitis












 Atopic dermatitis and contact dermatitis differ in certain ways.

Atopic dermatitis

Atopic dermatitis (AD) is the most common type of eczema, so some people simply call it eczema. It causes people’s skin to become discolored, itchy, cracked, and dry.

It is a chronic skin condition that occurs throughout an individual’s life. Eczema runs in families and often occurs in people with a family or personal history of asthma and hay fever. AD usually begins in childhood.

Contact dermatitis

Contact dermatitis (CD) is also a skin condition where a person develops skin redness, inflammation, and other lesions after coming into contact with an irritant or allergen that triggers an allergic reaction.

There are two types of contact dermatitis: allergic (ACD) and irritant contact dermatitis (ICD).

ACD refers to a person experiencing an allergic reaction following skin contact with an allergen, while ICD results from an external factor that damages a person’s skin.

People with celiac disease have a higher risk of developing DH, as the condition is a skin manifestation of the s...
