I always have a large bottle of this at home, and a smaller travel sized bottle in my hand bag, it is fantastic for when you out and about and cannot wash your hands.
I suffer from palmers hyperhidrosis (meaning my hands are often sweaty/moist) and this has been something that has affected my whole life. It causes a whole lot of stress and anxiety when I am around people, or when I have to fill out forms, or even when driving if it gets really bad. Dettol hand sanitizer offers a short temporary relief and drys my hands up even if only for a few minutes which allows me to fill out paper work without smudging ink or wetting the paper, and shake hands without being anxious. I have found nothing else that works for my hands, even if this is only a very short temporary relief, it makes my life easier.
It does not work EVERY time for me, as sometimes my hands are just to bad on the day, but I am still thankful to have it. :)
This is really one of those products a girl needs to carry around in her bag. All the time. I have a travel sized one which I often replace when it has finished, but I regularly use it if there's no where to wash my hands. Especially when touching things like trolleys, escalator sides and elevator buttons.
Tips: Carry a travel size one in your bag
