What should be done before applying a topical medication?

Ensuring that the skin is clean and dry before applying a topical medication is essential for effective treatment. This step removes potential barriers such as dirt, oils, or other substances that could interfere with the medication's absorption into the skin. A clean surface allows for better penetration of the medication, helping it to achieve its therapeutic effect more efficiently.

In addition to promoting effective medication delivery, a clean and dry skin surface minimizes the risk of irritation or infection that could arise from applying a product over unclean skin. Taking this precaution helps ensure that the treatment is both safe and effective for the individual receiving it, aligning with best practices in medication administration.
