A deodorant aims to combat unpleasant odors caused by bacteria that proliferate on the skin. It contains deodorizing ingredients that fight these bacteria, thereby reducing or preventing odors. Deodorants typically do not contain ingredients that reduce sweating themselves. Instead, they mask odors or combat the cause of the odor. An antiperspirant, on the other hand, aims to reduce excessive sweating by temporarily blocking or constricting the sweat glands.
