Deodorant crystal
Crystal deodorant is a completely natural product and consists of potassium alum. They have drying, antibacterial, anti-inflammatory, wound healing, cleansing and absorbing effects. There is no aluminum hydrochloride in the crystal.
Salts of this deodorant don't penetrate the pores and don't accumulate in the body. The crystal will not reduce perspiration, but it will allow sweat to dry faster on the surface of the skin: armpits will be dry and there will be no marks on clothes.
Deodorant-crystal must be applied to damp, clean skin of the body, and be sure to moisten before use, otherwise it will not work. The crystal is fragile; if it falls to the floor, it will break. The product doesn't have any smell, and this isn't a plus for all people. It will not cope with profuse sweating and will not save from wet stains on clothes.
