I bought perspirex lotion from guardian.
Its a 100ml bottle.
I apply it once a day for the first 3 days.
Then 3 times a week after that.
Its a clear colourless solution the consistency of water.
I put a few drops on my palm and rub my hands together, like putting on hand lotion. Let it dry via blowing with a fan. Then go to bed.
The next morning, i wash it with warm water and soap.
It also helps if you have some moisturizing hand lotion to put on as your skin may be dry for the day. I find that this is because sweating actually moisturizes my skin, and applying this will stop my palms from sweating a lot. Probably cut down 80-90% of my hand perspiration.
Please do not touch your face before the lotion dries. Especially your eyes/tear glands.
It can be found at guardian for SGD28 or RM47 in JB. Please note that not all guardian shops sell it. I know the one at Funan has, as well as Plentong Giant (JB) has.
It works the same as gricrol - SGD21/60ml (spelling mistake) just that it comes in a bigger bottle.
A note of caution, NEVER EVER use it on damp/wet skin.
