What skin condition is characterized by red, itchy patches?

The condition characterized by red, itchy patches is eczema. Eczema, also known as atopic dermatitis, is a chronic inflammatory skin condition that often presents in the form of dry, itchy patches on the skin that can appear red and inflamed. This skin condition is particularly prevalent in children but can occur at any age, and it often varies in severity and can be triggered by various environmental factors such as allergens, irritants, and stress.

While rosacea also leads to inflammation and redness, it primarily affects the facial area and tends to cause more flushing and visible blood vessels rather than the itchy patches seen in eczema. Psoriasis, on the other hand, typically appears as thick, silvery scales over red patches rather than being characterized by itchiness. Alopecia relates to hair loss and does not involve skin patches or inflammation. Understanding these key differences helps in the recognition and treatment of these various skin conditions.
