a slow poison [SEP] i really liked the charcoal magnesium variety used it for one month was not able to find it in the store so i switched to lavender sage after a few days of using lavender sage i got a painful alkaline burn i have discovered this is due to the high baking soda content of these products i tried to switch back to the charcoal magnesium and encountered the same issue i really want to keep using them but my armpits got dark and were extremely painful i am now using the sensitive skin variety which is baking soda free not sure why they do not just make all of them baking soda free as it is not a good thing to have in contact with your skin all day
