Don't fall into those sorts of over promises. There is absolutely no guarantee that it will work for you. It's different with all people. You also need to use it in conjunction with other hair removal methods, like waxing or shaving.
It may reduce hair growth in the future, but it'll not be permanent.

its not permanent,you'll need to apply the product twice a day,
it does inhibit hair growth and you might shave a bit less often but after a while it becomes quite expensive.

i suggest to try laser hair removal instead.
