Of course if you read what the manufactures say, it almost sounds like your are getting an internal facial. What is being promoted is Hyaluronic acid injection to create more volume high in the skin. This is a very helpful options. However these particular products are not the only products in these lines that can be used for these purposes. I tend to like products are are not quite so "smooth." The smooth characteristic also means that the product does not want to hold well were it is placed and tends to run. The actual longevity is good. However, there are times where you really want the filler product to hold were you place it.
