    What the gurus are saying

    This antiperspirant works by forming tiny plugs inside your sweat glands to block and reduce sweating, delivering prescription-strength results without needing a prescription. Dermatologists recommend applying it at night so the plugs can form properly, with visible benefits showing the next day. It comes in both a standard formula and a spray version for treating larger areas like your back.

    "For hyperhidrosis, my first-line over-the-counter recommendation is Certain Dri. It is a prescription-strength over-the-counter product that does not require a prescription, and I am not sponsored by this company. It is made up of 15% aluminum chloride, which creates a tiny little plug in your sweat gland, reducing sweat gland activity so [...] you do not have as heavy sweat marks in your underarms. You can also get the spray version for larger body surface areas like your back. The best way to use it is to apply it at night, so it can form those plugs and start working, with benefits showing the next day."

    "You also have Certain Dri, this is another good antiperspirant. It contains aluminum zirconium tetrachlorohydrex glycine, that's what goes down into the sweat gland and helps it involute and reduce the output of sweat."
