I was just starting to develop some fine lines around my eyes and on my forehead, and this product definitely took care of them. Unfortunately, like other reviewers, I, too, have often received a bottle whose top isn't screwed on entirely (same thing when I order directly from Luzern, so it must be a manufacturing issue). Nevertheless, the product works well and lasts a long time. I'm especially impressed with how well it works considering how "clean" its ingredient list is.
