[Introduction to antiseptics]

Antiseptics are anti-infectious agents for local use on the skin or mucosa, which distinguishes them from disinfectants, which are used on inanimate surfaces usually because of their toxicity. The present article explains the differences among the multiple possible antiseptics; special attention is paid to the most common, such as alcohol, chlorhexidine, povidone iodine, and oxygenated water. Finally, we stress the different antiseptic formulations, which increase the usefulness of these agents in specific indications.
