Itching is a vague symptom that can have many causes such as insect bites, allergic reactions (systemic or contact), or dry skin. All of the causes may be problematic to the person who has an itchy face; however, I imagine you wish to know when it is dangerous? Itching caused by hives associated with a severe allergic reaction or anaphylaxis would require emergent medical attention.
