I do not have a huge problem with sweating, however I like to try everything new, so I had to try  it.  So glad I did.  I love that you put it on at night.  No more deodorant stains!  I use not to sweat much, now I do not sweat at all!  Even better I do not have any kind of odor under my arms.  I have sensitive skin and this does not bother me at all.
