What is facial cellulitis?

Cellulitis is a common but potentially serious bacterial infection of the skin that can affect any part of the body, including the face, states Mayo Clinic. Cellulitis in adults frequently affects the legs, face or arms, while in children, facial or anal cellulitis is more common, according to WebMD.

Most cases of cellulitis are mild and clear up within a couple of weeks after antibiotic treatment. Sometimes cellulitis can develop into a more serious infection that leads to sepsis, an illness that affects the whole body, says WebMD. Diabetics and those with a weakened immune system or edema are more prone to cellulitis as well as to recurring attacks.
