Facial hyperhidrosis. Use it on face?

Suffering from craniofacial hyperhidrosis ( excessive forehead sweating ) in daily life , it makes my confidence too low during social interaction.....so I take opinion from dermatologist online and he prescribed aldry lotion on forehead to prevent excessive sweating but there is no improvement .....so I heard about certain dri ( one of the strongest antiperspirant for hyperhidrosis ) which are available on Amazon ....so is it safe to use on forehead to prevent excessive sweating ? Is there any side effect of certain dri antiperspirant when use it on face? And I can't afford botox so kindly suggest antiperspirant which one is strong and effective better than aldry as it was not working fro me Plz note - my all reports are normal including thyroid
