Stick deodorant is a personal care product designed to reduce body odor caused by sweating. It typically comes in a solid form that is applied directly to the skin, usually in the underarm area. Stick deodorants often contain ingredients like aluminum compounds, which help to block sweat glands, and fragrances that mask odors. Many stick deodorants are formulated to be long-lasting and may offer additional benefits, such as moisturizing properties or skin-soothing ingredients. They are convenient to use and can easily fit into a bag or purse, making them a popular choice for daily hygiene routines.
