Frequently asked questions

The following are the most frequently asked questions about Secret Clinical Antiperspirant.

Q. What is the difference between antiperspirant and deodorant?

A. The difference between antiperspirant and deodorant comes down to their ingredients. In most cases, antiperspirants contain an active aluminum ingredient (which helps with sweat control), while deodorants do not. Because of this, many patients with excessive sweating benefit from regular antiperspirant use.1

Q. Why is night application of antiperspirant more effective?

A. Antiperspirant helps manage excessive sweating by creating shallow plugs that slow the production of sweat from the axilla. During the day, we have a higher body temperature and are more likely to be active, which results in the creation of less effective plugs. Overnight, we have a lower resting body temperature and a slower sweat rate, which allows for the creation of more effective plugs. With this in mind, we recommend instructing your patients to apply Secret Clinical Antiperspirant at bedtime for the best results.
