Hi guys.... I am new to this forum. I just bought a galvanic machine. Some tutorial says the pole that is held by client needs to be wrapped in wet cloth and other tutorial says the pole can be held without anything (ie. skin - metal direct). Which one is correct? Also, some says baking soda solution needs to be applied to the treated skin, other says specific galvanic gel before any skin serum. Which one is correct? If anyone knows about how to operate galvanic machine, please please share..... Thanks a lot!!!!
