I was skeptical when we were first placing the order. But I thought why not? So it arrived last week and I have been using it nightly before bed (as the instructions say). I haven't had any negative side effects so far. This is why I am always leery of ordering eye products because they go on your eyes. But this doesn't burn or anything. It goes on wet and clear. I wait for it to dry some before laying down, as I don't want it to get wiped off.
So far I haven't noticed a difference but it has only been a week and the box clearly states three weeks.
So I will update my review in a couple weeks to let you know the results. But so far currently I am pleased with this product.
