What is the purpose of using an antiperspirant?

The purpose of using an antiperspirant is specifically to help stop or reduce sweat. Antiperspirants contain active ingredients, such as aluminum compounds, that temporarily block the sweat glands. This action reduces the amount of sweat that reaches the skin's surface, which can help control moisture and contribute to feeling drier throughout the day.

Unlike deodorants, which primarily address body odor by masking or neutralizing the smell of sweat, antiperspirants focus primarily on minimizing the production of sweat itself. Therefore, when considering the role and mechanism of antiperspirants, it is clear that their primary function is to manage perspiration, making the chosen answer accurate.
