Which skin condition is characterized by red, inflamed, and swollen areas?

Cellulitis is a skin condition characterized by red, inflamed, and swollen areas, often appearing warm to the touch. It results from a bacterial infection that typically affects the deeper layers of the skin and subcutaneous tissue, leading to the described symptoms.

The redness and swelling indicate an inflammatory response as the body fights off the infection, which can occur following a break in the skin such as a cut or bite. Prompt medical treatment is essential, as cellulitis can spread rapidly and lead to serious complications if not addressed.

While conditions like psoriasis and eczema also involve inflammation and may cause redness, they have distinct characteristics. Psoriasis is marked by thick, silvery scales, while eczema typically presents with dry, itchy patches. Chloasma, on the other hand, is a pigmentation condition that presents as brownish facial discoloration, and does not involve the inflammation and swelling characteristic of cellulitis.
