I was very skeptical about the effect of this lotion. I decided to buy me because of the positive reviews from other customers. I have had good experiences. After only two days, I have found a significant reduction in sweating on head, forehead, neck and face. The lotion is pleasant to apply, greasy and does not smear. Side effects I could not tell. Surely every skin type reacts differently, and perhaps the same effect is achieved not everybody, but I can recommend it to try with SweatStop at least. I'm very satisfied.
