Aluminum-based compounds are one of the active ingredients used in deodorants (particularly deodorants that contain antiperspirants). Their primary role is to block the skin pores temporarily from producing sweat. Aluminum is a reported neurotoxin, which can inhibit 200+ biologically vital functions in the body. It can cause adverse effects in humans, plants, and animals.
Research Says: When the skin absorbs the aluminum compounds from deodorants, it can interfere with the way estrogen receptors of breast cells function. Here is a study that confirms this statement. It also promotes the growth of cancerous & non-cancerous cells. According to scientists, consistent use of aluminum-based deodorants might increase the risk of breast cancer.
