Antiseptic solutions are substances used to reduce or eliminate harmful microorganisms on living tissues, such as skin. They are commonly used in medical settings to prevent infections during surgeries or wound care. Common examples include alcohol, iodine, and chlorhexidine. These solutions work by disrupting the cell membranes of bacteria and other pathogens, making them ineffective. Antiseptics are different from disinfectants, which are used on non-living surfaces. Proper use of antiseptic solutions is crucial for maintaining hygiene and promoting healing in various healthcare situations.
