Eczema (Contact Dermatitis)

Eczema, also known as contact dermatitis, is a type of skin inflammation that occurs when the skin comes into contact with an irritant or allergen. It is a common condition that affects people of all ages and can cause significant discomfort and distress.

Types of Contact Dermatitis

• Irritant Contact Dermatitis: This type of dermatitis occurs when the skin comes into contact with an irritant, such as soap, detergent, or acid. It can also be caused by friction, heat, or cold.
• Allergic Contact Dermatitis: This type of dermatitis occurs when the skin comes into contact with an allergen, such as poison ivy, nickel, or certain chemicals. The immune system reacts to the allergen, causing inflammation and skin damage.
• Photocontact Dermatitis: This type of dermatitis occurs when the skin is exposed to sunlight after coming into contact with certain substances, such as perfumes or medications.
