Makeup primer is one of those beauty secrets that can make a big difference in the look and wear of your makeup. It preps your skin for makeup and creates a smooth base that makeup can adhere well to. If you’ve tried a foundation that looks fantastic on a friend or a model in a magazine only to be disappointed with the results, using makeup primers can make a big difference. Even if you are happy with the foundation you are currently using, a layer of cosmetics primer underneath can bring it to a whole new level.
