Not knowing the difference between deodorant and antiperspirant
Antiperspirants reduce sweat, while deodorants reduce odour.
According to Fayne Frey, dermatologist and founder of FryFace, most antiperspirants contain aluminum salts, sometimes mixed with a zirconium salt, which bind to a protein in the sweat gland ducts. This creates a sweat duct plug that temporarily tamps down sweat production. Deodorants, on the other hand, are topical products that either neutralize odourusing ingredients that kill some of the bacteria that contributes to the development of body odouror simply mask it. “They do not reduce the amount of sweat expelled and will not keep your armpits dry,” explains Tsippora Shainhouse, MD, FAAD, board-certified dermatologist in Los Angeles and clinical instructor at the University of Southern California.
