I live in Hong Kong and I use idromed 5 for hands and sweatblock for face and scalp. Works fine for me, you should try
I just buy it from the main sweat block site. Came in less than 2 weeks. Just dab it across your forehead instead of wiping it cuz it'll cause irritation. Works really well, no sweat at all at the places I applied. For hands, I do it for 1 week straight initially then 3 times a week after. It was great especially during summer since it gets so humid, let me know if you need advice in hands, I've been using it for 4 years
