Query: first timer

I'm a 16 year old girl who has had sweat rings since the end of 8th grade. I mostly sweat perfusivily when I am nervous, which is a majority of the time since I'm extremely shy. But I also sweat just sitting on my couch. The rings can get really big sometimes and it's extremely embarassing. It is my second day trying Certain Dri: yesterday it didn't work, but tonight as I put it on I actually felt itching and burning, unlike yesterday. So I believe I did something wrong the first day. The itching is somewhat intense considering I have sensitive skin, but I feel like it just may work. I'm hoping so because I have no other alternitive.
