I will start my primer series with Mac Prep and Prime Skin Visage as this is the first primer that I own. I got a sample of this, 2 or 3 years ago and fell in love with it and bought the full size after finishing it. This primer is silicone base and very smooth to apply. It has light reflecting particles that I can describe as eensy weensy glitters. These particles reflects light thus giving you a glow-y look after putting on the foundation. It doesn't look very glittery, don't worry. It gives the right amount of shine to achieve a perfect dewy look. As it has light reflecting particles, this primer is best to use with dewy finished foundation than matte ones.
