Baby powder is a fine, powdery substance commonly used to absorb moisture and reduce friction on the skin. It is often made from ingredients like talc or cornstarch, which help keep the skin dry and comfortable. Parents frequently apply baby powder to their infants to prevent diaper rash and irritation. In addition to its use for babies, baby powder can also be used by adults for various purposes, such as freshening up shoes or absorbing sweat. However, some concerns have been raised about the safety of certain ingredients, particularly talc, which has been linked to health issues in some studies.
