Can bath powder with baking soda and corn starch harm you?

Bath powder containing baking soda and cornstarch is generally safe for most people when used as directed. Baking soda can help soothe skin irritation, while cornstarch may absorb moisture. However, excessive use may lead to skin dryness or irritation in some individuals, especially those with sensitive skin. Always perform a patch test first and consult a healthcare professional if you have concerns.
