You have to pass it multiple times a day. It wears off in minutes.
Disappointed. I saw the review videos and I was very hopeful for the nerdwax to solve my problem of slipping glasses. It is not worth the money. Just pass regular wax and keep your money. In the first day, I passed it a total of 10 times as it lasted only minutes. It is specially crappy for people with oily skin.
