Antiperspirants are personal care products designed to reduce sweating and control body odor. They work by blocking the sweat glands, which decreases the amount of sweat released onto the skin. Most antiperspirants contain active ingredients like aluminum compounds that temporarily form a gel to plug the sweat ducts. These products are commonly applied to areas such as the underarms and feet. While antiperspirants are often confused with deodorants, the key difference is that deodorants mask odor, while antiperspirants actively prevent sweating. Many people use antiperspirants daily for comfort and confidence in social situations.
