What is the main function of an anti-perspirant?

The primary function of an anti-perspirant is to reduce the amount of sweat on the skin. Anti-perspirants contain active ingredients, such as aluminum compounds, that temporarily block the sweat glands. This reduction in sweat production not only helps in keeping the underarm area drier but also plays a crucial role in minimizing body odor, as sweat itself is odorless; it is the bacteria that break down the sweat that can cause unpleasant smells.

Understanding the main purpose of anti-perspirants clarifies why they are specifically formulated to target perspiration. Other options, while related to body care and odor control, do not align with the primary purpose of an anti-perspirant. Masking body odor involves fragrances, enhancing skin hydration pertains to moisturizers, and increasing skin temperature does not relate to the function of anti-perspirants at all.
