Good temporary benefits
The positive points include the facts that it results in a much more effective blurring of lines than any primer I have ever used and it requires very little product to deliver these results. The down sides are the very temporary - a few hours- results before the "creases" return and the cost. It is definitely not botox in a jar! I have only been using it less than two weeks and so I cant speak to long term benefits, but the ingredient list is favorable.
This is "almost Botox" in a bottle, and almost as expensive as Botox, but really helps my wrinkled brow lines, which were suppose to be "fixed" (or at least improved) when I had an endoscopic brow lift in Dec 2014 ( did not work)
