In chronic wounds, in addition to not having a clear effect on bacteria organized and protected in biofilms, they can produce bacterial resistanceand trigger allergic reactions. In fact, in clean acute wounds, such as those secondary to dermatological procedures, although the use of topical antibiotics is not indicated, it is a very widespread practice (see post: “ How do we manage clean wounds produced after dermatological procedures?“).
