The directions are simple and easy to read. Just apply a dime-size amount of product. In my opinion, and with my experience, there's no need to go overboard with the product. I’m not quite sure the plumping cream did anything as we didn’t notice any changes.
The prolonging cream, however, worked how it was marketed. Took just enough sensation away to go a little longer. All while not completely numbing. Really, adds just the right amount of sensation (or lack of it). This could be useful to those trying to add a little time to their experience.
I’m sure it is possible that I had a different reaction to the plumping than others may or may not have. I say try it out just because the prolonging worked so well.
