I sweat so much! Does anyone have any tips?

I was wondering if anyone had any tips on excessive sweating??
I sweat SOOO much on my face! No matter what weather, what temperature I sweat! It's excessive and getting in the way of my work.
It's so embarrassing I hate excerising because my sweat drips everywhere from my face!
I have seen my GP and she had done bloods and simply said that there's no causes or treatments other than Botox.
From what I can research, Botox is only used in the armpits.
Has anyone used Botox for excessive swearing on their face?
I should mention that I have also tried anti-persperant facial creams too..
please help!! I HATE it!! 😭
