My experience with Hydrosal gel
Hi, yes I've tried Hydrosal gel. It works much better that CertainDri or Drysol because it's in a salicylic acid gel which is better absorbed by the skin. It was developed by world renowned expert on hyperhidrosis Dr. Antranik Benohanian. He's in Montreal, Canada.
It can be very strong on the skin so I recommend you apply hydrocortisone cream or petroleum jelly in between your fingers BEFORE applying the Hydrosal gel. It will create a barrier so that the medication can work where it needs to work and not drip into the parts of your hand that do not sweat. At first I did not protect the skin in between my fingers and they became very red and started to peel and it not only hurt but it looked gross! So I learned the hard way.
Unfortunately for some people the aluminum salts in all these products can cause urinary retention - it might mess with your bladder. It happened to me and I just couldn't take it so I had to stop using it.
While I was using it I would say I saw about 75% relief from sweating. It didn't work completely but it helped a lot. My fingertips were still a little bit moist but not nearly as bad as before. It makes you feel more in control and less like a wet mess.
