Dior Show Maximizer or Urban Decay Eyelash Primer? My pick is Urban Decay. The formula is slightly thicker so it takes less work to build up product. The brush is smaller, which is just a preference of mine. Plus, Urban Decay is several dollars cheaper, which is always good! They are both excellent products! Nothing wrong with either one of them. You can’t go wrong!
I purchased the items featured and was not paid to mention them. As always, these are my own honest opinions:)
