Actually,, this foundation can be anywhere from light coverage, all the way to full coverage, depending on the application technique *fingers, Beauty Blender, stippling brush, buffing brush, ets.," as well as how much you build it up. I DO suggest using a primer under it, preferably one that is mattifying, and then set it with a powder, if you tend to have oily skin. Otherwise, if you have dry skin, I still recommend a primer, but it doesn't have to be a mattifying one, and really no need to use a powder, unless you're like me and just feel more comfortable doing so. With combination skin, again I would recommend a mattifying primer, particularly in your oily areas, which tend to be the T-Zone, and you can set that area only with a mattifying powder, or if you're more comfortable doing so, you can set the entire face with setting powder.
