I recently got botox on my hands, but there were spots that were missed. When I was younger (16-17) I used drysol for a little over 2 years (I am now 20). I read a lot of articles on how aluminum is very bad for your brain and that it gets stored in your brain and in your bones. Would it be okay to use certain dry on my hands for three months while I am at college? Or should I avoid it all together? I have tried everything else. (Iontophoresis takes too long).
