Which skin condition is characterized by redness and inflammation?

The condition characterized by redness and inflammation is dermatitis. Dermatitis is an umbrella term for various skin inflammation disorders that typically manifest as red, swollen, and itchy skin. It can arise from a variety of triggers, including irritants, allergens, or even environmental factors. The inflammation leads to redness and discomfort, making it distinct from other skin conditions that may not primarily present with these symptoms.

Psoriasis, while it can also cause redness, is primarily identified by the presence of thick, silvery scales on the skin, which differentiates it from dermatitis. Eczema, on the other hand, is often considered a type of dermatitis and includes such symptoms as itching and dryness along with redness and inflammation, but in this case, dermatitis serves as a more specific term encompassing a broader range of inflammatory skin disorders. Alopecia, on the other hand, refers to hair loss rather than a skin condition characterized by inflammation.
