What should you know about impetigo drying up?

Sores may stop oozing, become less swollen, and develop a dry yellow-brown crust as the skin begins to repair. A dry surface does not prove that bacteria are gone. New spots, spreading redness, tenderness, or fresh fluid suggest that the infection may still be active. Crusting can also occur with other skin conditions, including atopic dermatitis, so appearance alone cannot confirm the diagnosis.

Wash your hands before and after touching the area. Clean gently with lukewarm water, soften crusts rather than picking them, and pat the skin dry. Keep lesions covered with a clean dressing when practical, avoid sharing towels or razors, and launder clothing and bedding that touch the sores. A clinician may recommend [Topical Antibiotic Therapy](/treatments/medical-dermatology/topical-antibiotic-therapy/) or [Antibiotics For Skin Infection](/treatments/medical-dermatology/antibiotic-therapy-for-skin-infection/) depending on the number, location, and severity of lesions. Use medicine exactly as directed.

Arrange medical advice if sores are spreading, recurring, painful, or not clearly improving. Seek prompt care for rapidly expanding redness, marked swelling, fever, severe tenderness, or involvement close to the eye. Do not scratch or remove crusts forcefully while waiting.

Ask whether the crusting fits impetigo, whether treatment is still needed, how long to keep lesions covered, and when close contacts can safely share towels or return to usual activities.
