Louis Widmer Deo Sprays are designed to reduce excessive perspiration while effectively neutralizing odors, without harming the skin or causing allergic reactions. The active ingredient, aluminium chlorohydrate, is known to be effective against excessive sweating, while ethylhexylglycerin helps inhibit the growth of bacteria that cause unpleasant odors. These deodorants are suitable for use under the arms, on the hands, and feet, and can be used to treat excessive sweating in the folds of the body over a long period of time.

For best results, one application per day is usually enough, but those with hyperhidrosis may benefit from using the deodorant twice daily. The maximum efficacy of the product, which provides antiperspirant protection for up to 24 hours, can be achieved after 2 to 3 days of regular use. These deodorants are mild and gentle on the skin, even on irritated or reddened skin in the armpit region.
