Egzama is a common skin condition that causes inflammation, redness, and itching. It can appear as dry, scaly patches or blisters on the skin. Egzama can affect people of all ages, but it is most often seen in children. The exact cause is not fully understood, but it is believed to involve a combination of genetic and environmental factors. There are several types of egzama, including atopic dermatitis, contact dermatitis, and seborrheic dermatitis. Treatment typically involves moisturizing the skin, avoiding irritants, and using topical medications to reduce inflammation and itching. In some cases, doctors may recommend allergy testing to identify triggers.
