Time to get thinking. An antiseptic is a substance that destroys, or stops the growth of, germs on living tissue. They must be strong enough to fight germs but mild enough not to irritate sensitive tissues. Antiseptics should not be confused with disinfectants and antibiotics. An antiseptic cream that causes the death of bacteria is called a bactericidal cream or antibacterial cream and is useful for preventing cuts, scratches and insect bites from becoming infected.
