Deodorants are personal care products designed to help reduce body odor caused by sweat. Sweat itself is odorless, but the bacteria on the skin can break down sweat and produce an unpleasant odor. Deodorants work by masking or neutralizing this odor, often using ingredients like antimicrobial agents or fragrances. It's important to choose a deodorant that works well for your body and to avoid using deodorants on broken or irritated skin. Additionally, natural deodorant alternatives are becoming increasingly popular, which use ingredients like baking soda, coconut oil, and essential oils to combat body odor.
