What is the difference between clinical strength and regular antiperspirant?

Clinical-strength formulas generally use a higher concentration of aluminum-based active ingredient and advertise longer protection windows (often 72 to 100 hours per application claim). Regular antiperspirants use lower concentrations aimed at typical daily sweat. Among these candidates, listings like Secret Clinical, Degree Clinical Strength, Gillette Clinical and Certain Dri position themselves for heavier sweat needs, while the standard Degree sticks target everyday use.
