Choosing the correct skin antisepsis technique is an important consideration before invasive procedures. Nurses are commonly taught to apply antiseptic using circular motions, moving from the intended insertion site outward, while other protocols emphasize back-and-forth friction. But does the direction of application actually affect microbial reduction? Research comparing these methods has produced findings that depend partly on the antiseptic formulation and study conditions. Understanding these differences helps nurses distinguish established infection-prevention practices from assumptions based on traditional teaching. This article examines the evidence and translates it into practical guidance for nursing practice.
