7. Use Anti-Chafing Powders and Cornstarch Alternatives Safely

Anti-chafing powders can help keep the area dry and reduce friction. Opt for talc-free powders or cornstarch alternatives, which are safer for routine use.
Apply a light dusting to the area, being cautious not to inhale the powder. Avoid using cornstarch if a yeast infection is suspected, as it can sometimes feed yeast growth.
