Trying this new thing...Tip...?

So one of the "perks" of living in Florida is the heat and humidity...dear me, the humidity! It kills me haha if I hate anything, it's sweating. So I'm trying this new thing that I read about a while go. Smeone said use deodorant on the areas of their face that sweats the most. So this morning I tried it out, and so far, I've noticed less sweat. I'm wondering if this is gonna be any good for my skin haha I'm not sure if this is a tip or me being foolish and believing everything I read on the Internet haha
