Definition

Noun: A cosmetic product, typically a liquid, roll-on, spray, or solid, applied to the skin (usually under the arms) to reduce or prevent sweating (perspiration). It works by temporarily blocking the sweat glands.

Usage

Antiperspirants are used for personal hygiene to manage body odor and wetness caused by sweat. They are distinct from deodorants, which primarily mask odor but do not significantly reduce sweat production. - Apply the antiperspirant to clean, dry skin for best results. - Many antiperspirants also contain deodorizing agents.

Examples

Advanced Usage
