Eczema is a skin condition which affects adults and children, and it often gets worse when you start scratching the affected area. The term eczema is a general term which applies to symptoms of a recurring skin rash, which are often accompanied by: redness, swelling, dryness, itching, crusting, flaking, blistering, cracking, oozing, or bleeding.
The 3 main types of eczema

General symptoms include dry, itchy skin and rashes on the face, inside the elbows, behind the knees, and on the hands and feet. Atopic dermatitis is a hereditary condition.
Contact eczema is a rash that’s caused as a result of coming into contact with an allergen. The most common allergens/irritants are laundry detergents, but it can also be caused by stinging nettles or poison ivy. The rash is usually localised to the area in contact with the irritant.
