The product does what it promises. After a few days of use, the shoulders remain dry. No more sweat stains on shirts or shirts. The first few days you have it so every evening spraying. After 3 times it burned pretty neat to me. I nevertheless persevered 5 applications. Since then, I use it only about every 3 days but it causes extreme itching. It is hardly impossible not to scratch. I'll have it, unfortunately, probably settle because the itching is really unbearable.
