You only need the tinest amount of powder to set your foundation so it will last all day long. I use a powder puff and just lightly dab it on my skin in the morning and I'm done. I don't need to touch it up at all. This powder does have a bit of a luminous effect but it doesn't emphasize pores or acne pot mark scars.
