i am not very experienced w/make up, i had never even heard of primer till about ten seconds ago, but basically i have combination skin and i would like to be able to apply make up so that it doesnt look like i'm wearing it and not have to do other things to my face. in my mind my pores are very noticeable-i would like to know what i can buy to make my face look smoother "poreless" lol, any advice on what exactly a primer is and then which to buy along with foundation would be great, i am looking to be able to buy from walmart or a store not something i have to order online. i so appreciate the help
