I had tried many products to reduce excessive perspiration but none had worked. I found driclor on a search and decided to try it. At first there was some irritation but it has worked wonders. I've been using it for nearly 2 months now and can go for about 3-4 days without applying. It has made me so happy not having to worry about sweat stains. I would recommend it to my friends but would advise about irritation if they had very sensitive skin.
