Suggest Treatment For Facial Hyperhidrosis?

Hello, I have been suffering from severe hyperhidrosis on my face for the past 4 years now and I am 20 years of age. I've seen several doctors in the UK and also India, but i have not
found a result. I am deeply self conscious and moreover I have combination skin, which can also become extremely scaly and dry. Can you please advice me on how to treat first the hyperhidrosis on my face and secondly the combination skin.
Thankyou.
