With Antihydal Ointment I got my hyperhidrosis (excessive sweating) of palms and soles finally under control. Unlike conventional antiperspirants based on aluminum salts, and did not work with me to the affected areas, is the active component in Antihydal methenamine, which constricts the sweat glands. The water-based ointment is best performed at night, plus it is applied thinly to the corresponding skin. Antihydral dries after a few minutes (which is of course at the beginning of the treatment does not work so well), I prefer it but anyway, to wear overnight socks or fabric gloves to distribute any ointments dust. After initially daily use (you can do it yes but then do not expect!) Has set the action after a few days, since I use Antihydral in 1-2 nights per week. A side effect is that a slightly thickened corneal layer forms, which easily takes on a yellowish tint, therefore, the application should not be exaggerated as well. However, this can get with a pumice stone easily under control. Also electric callus remover and manicure / pedicure appliances in good stead here. Furthermore, this corneal layer fluoresces under UV light which you should keep in mind if you are staying in places with blue illumination. However, this effect can also be used in order to better identify the cornea, and to remove the equipment described. Another side effect is that the skin becomes too dry. Somehow I can this problem not so take very first, but the skin becomes easily cracked, and according to a statement of a doctor is an increased risk of contracting an eczema. With hand creams can be here easily remedy. All in all, there is indeed an increased maintenance effort, but in my opinion not worth mentioning compared to the distress and inconvenience which it is exposed by the constant, strong sweating. Moreover, I find it incredible that many dermatologists do not know this simple, inexpensive and almost no side effects solution, especially as alternatives (antiperspirants, electrophoresis Disconnect, nerve, Botox) were no good alternatives for me.
