for the past 3yrs i have been having serious sweat problems on my armpits. i have tried countless types of anti persperant roll ons,sprays,gels, talc etc but seconds after i have applied them everything just gets wet again and soaks my shirt around the area. even when i wear an inner t-shirt to at least absorb the moisture it does little good. im 30yrs and slim. i know africa can be very hot but i never realy to faced this problem before now. are their realy heavy duty anti persperant products out there i can try? thanks
