How long does it take to work and how long does it last? Is it the kind that takes a while to show improvement but lasts longer or does it work immediately and last a shorter amount of time. In fact, how long does it last in either case? What percent of folks who only need frown line done between the eyes only need 60 units?

It takes 3 days to 2 weeks to see the results. They will then last for 3-4 months. The number of units needed will vary per person. Unfortunately, we do not have the exact percentage.
