Causes of impetigo on the face

The skin normally acts as a barrier. Scratching an itchy patch, rubbing a bite, shaving, blowing the nose repeatedly, or letting a small cut become irritated can create an opening. Bacteria from hands or close skin contact can then multiply on the surface. Eczema and other conditions that cause dry, cracked, or itchy skin can make scratching more likely; learn more through [Atopic Dermatitis](/conditions/atopic-dermatitis/). Impetigo may then produce blisters, shallow sores, fluid, and crusting. [Crusting Skin](/symptoms/skin-crusting/) is a symptom, not a diagnosis, so similar-looking facial rashes need proper assessment.

Avoid scratching and wash hands often, especially after touching the face or applying medicine. Keep nails short, cleanse gently, and pat the skin dry. Do not share towels, pillowcases, cosmetics, razors, or face cloths. Clean items that touch the affected area and pause irritating exfoliants or fragranced products. A clinician may prescribe [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) for a limited infection or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) when several areas are involved. The right treatment depends on the examination, location, extent, and overall health.

Arrange prompt medical review for a facial sore that is spreading, increasingly painful, warm, swollen, or draining. Seek urgent care if there is fever, rapid worsening, eye pain, vision change, marked eyelid swelling, or severe facial swelling. Review is also sensible when sores recur, do not improve with the prescribed treatment, or appear in a person with reduced immunity. A repeated pattern may need assessment for an underlying itchy or irritated skin problem, ongoing contact trigger, or another diagnosis.

Ask which skin break may have allowed infection to start, whether an itchy rash or product is contributing, and how to protect the area while it heals. Ask whether close contacts need precautions, how long treatment should continue, and which recurrence signs warrant another examination.
