Why is removing crusts important in the treatment of impetigo?

Removing crusts in the treatment of impetigo is crucial because it allows for antibiotic effectiveness. Impetigo is characterized by crusty sores on the skin, and these crusts can hinder the penetration of topical antibiotics. When the crusts are removed, the antibiotic can better adhere to the affected skin and work effectively to eradicate the bacteria causing the infection.

This approach also helps in reducing the overall duration of the infection and facilitates faster healing. While comfort and containment of the infection are important, their roles are secondary to the necessity of ensuring that the primary treatment, which is the topical antibiotics, is able to reach the site of infection adequately.
