Some causes of facial itching include eczema, psoriasis, dry skin, viral infections, internal diseases, and allergic reaction. Eczema is a skin condition that is characterized by itchy and scaly skin that can appear on the face, knees and hands, notes Healthline. The affected area can also be very dry or develop crusting skin patches that may ooze.
Dry skin, also called xerosis, may be the result of excessive bathing or environmental factors, such as low humidity conditions, states Mayo Clinic. Itching is a symptom of dry skin.
Allergic reactions are very common causes for a facial itch. A person can be allergic to cosmetics, facial products, medications, soap, foods and insect bites. In these cases, the facial itch can be caused by hives that manifest as part of the reaction. Contact dermatitis can also lead to an itchy face. This condition develops when a person touches or is in close contact with a substance, such as poison ivy, states Healthline. Seasonal allergies also may be another reason for this condition.
Another cause for an itchy face can be chickenpox, which is a viral infection. The main symptom of chickenpox is an itchy rash that can develop on the face and other areas of the body. There are also internal conditions that can cause the skin to itch, including different types of cancers, liver and kidney diseases, as noted by MedicineNet.
