What is the purpose of an antiseptic?

The purpose of an antiseptic is to discourage the growth of microorganisms. Antiseptics are substances applied to living tissue or skin to reduce the possibility of infection, sepsis, or putrefaction by inhibiting the growth of bacteria, viruses, fungi, and other pathogens. They are typically used before medical procedures, such as phlebotomy, to prepare the skin and minimize the risk of introducing infections.

In this context, antiseptics do not necessarily kill all microorganisms, which is the role of disinfectants that are used on inanimate surfaces. Antiseptics may reduce the number of pathogens to a safer level rather than eliminating them entirely. Additionally, while they may help in cleaning the area by reducing microbes, their main action is not primarily focused on removing dirt and debris, nor do they neutralize toxins. Their formulation and intended use are specifically designed to provide a level of microbial control rather than complete sterilization.
