What type of product is primarily used to kill germs on skin?

Antiseptics are specifically formulated to kill or inhibit the growth of germs on the skin. They are typically used on the skin to prevent infections, especially in a medical or salon setting where maintaining hygiene is crucial. Antiseptics often contain alcohol or other antimicrobial agents that effectively reduce the number of pathogens on the skin's surface.

In contrast, disinfectants are meant for non-porous surfaces and are not safe for use on the skin. Sanitizers, while they do reduce germs, are less effective than antiseptics when it comes to killing harmful microorganisms on the skin. Moisturizers primarily serve to hydrate the skin and do not have germicidal properties. Thus, antiseptics are the most appropriate products to use when the goal is to kill germs on skin.
