The Best for Me!
I have been using a lot of eye shadow bases and primers to cease the creasing. I seem to have a problem with my eye shadow creasing a lot. I have used UDPP and Too Faced Shadow Insurance. Both did not work very well for me when it came down to the creasing of my eye shadow. With MAC's prep and prime eye, I have yet to crease! I have not only used it with MAC shadows but other brands of eye shadows. Since it is so creamy, I do not need a lot to spread on my eyelids. Plus, I have only started using this product in the summer and so this product is going up against the hot weather. I personally find this the best of the primers and bases I have used. I know this varies but if you have yet to try it, it is definitely worth the chance!
