Do you believe in Magix?
I just discovered an inexpensive makeup primer called Magix Face Perfector by Avon. Before, I was just using an oil-free moisturizer as my primer before I put on my foundation, but I really didn't like that method. I've heard that Monistat Chafing Relief powder-gel can be used as a primer, but I have yet to try that (has anyone tried this?). After reading great reviews about Magix, I decided to give it a try.
I haven't tried any of the more expensive brands to compare this to, but to me, it works pretty good. I have very oily skin and this controls the shine for hours. It's a very light formula. When I apply it to my face, it justs sinks into my skin and it feels like nothing's there. I haven't worn it under makeup yet. When worn alone, it makes my skin feel so smooth and my pores are less visible. It's a keeper for me. At $10, you can't go wrong. Have you tried Magix yet?
