I perspire to much im a teenager?

I would look into a clinical strength one if you think that you are perspiring excessively. They sell them at the drugstore. They are a bit more expensive because they are prescription strength. If that still doesn't help you might want to just go talk to your doctor. There is such a thing where a person can have a disorder where they sweat a lot. Severe cases can be treated with botox injections into the sweat glands.
