"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."
