As mentioned earlier, there are numerous products on the market that claim to stop underarm sweating. However, many of these products simply don’t work or have very short shelf lives! If you want a product that works and will last for a long time without losing effectiveness, try using a combination of zinc oxide and antiperspirant instead.
Zinc oxide tablets can be purchased over the counter at most pharmacies in North America. They tend to cost about $5-10 US per box depending on brand/strength. Zinc oxide is also available as cream form from drug stores but I would not recommend this unless you have problems with application (i.e., it sticks to your fingers). A little goes along way so it isn’t expensive when compared against other treatments such as sprays and creams which usually must be applied 2-3 times daily costing anywhere between $20-$50 US per month!
