I used this sample on and off for several months. It created a powdery finish once worked into my skin. Once I covered it with foundation or powder, I wasn't so sure what effect it was really making with regard to coverage, endurance or the like. I was using other make up samples and not the makeup from this particular line so that may have lent to my experience.
The sample was long lasting although the very last amounts were difficult to use once I reached the end of the bottle. Overall I was impressed with the product. More than likely I will order it in the future.
