Well, we have two kinds of spackle in our household-one for our walls and the more fun Spackle to put on your face! I have been on the search for an under makeup primer that does not break me out and have tried many on the market. Laura Geller's Spackle does not feel like anyone else's primer. This primer feels more like a light moisturizer and gives off an opalescent hue to it. I like the feel of it so much that sometimes I do not even wear makeup over it. I never really thought I needed a primer until a few years ago when I would wear foundation and at the end of the day, I could not see the foundation on my face anymore. The purpose of a primer is to protect the integrity of the color of your makeup and creates a barrier between your skin and your makeup and I find with Spackle, I do not even have to touch up my makeup during the day. A little bit does go a long way and one tip that Laura Geller gives is to refrigerate the Spackle during the summer so it is cool when you put it on-it is quite refreshing!
