Chlorhexidine is also utilized as a surgical scrub or skin cleanser before medical procedures to prevent infections. It is known for its persistent and long-lasting antimicrobial activity, providing protection against a wide range of bacteria.

Furthermore, chlorhexidine is used for wound care to prevent infection and promote healing. It can be found in various formulations, such as gels, creams, and solutions, which are often applied topically.
