Understanding Pre-Procedure Skin Prep: Antiseptics Explained

Before a medical procedure, doctors typically use an antiseptic solution to wipe down the affected area. This solution is usually a combination of alcohol and iodine. Alcohol kills bacteria by disrupting their cell walls. Iodine is a broad-spectrum antimicrobial that can kill bacteria, viruses, and fungi.

The doctor will use a sterile swab or sponge to apply the antiseptic solution to the skin. The solution will be allowed to dry completely before the procedure begins.
