MAC’s Prep + Prime Finishing Powder is a silky translucent powder used to set your makeup. It’s available in one universal color that is said to suit every skin tone. Its great to use for touch ups throughout the day if you have oily skin. Translucent powders are great to use over foundation when you want to set it without adding extra coverage. It also helps reduce the appearance of pores, lines and other imperfections. I usually find myself reaching for these setting powders during the summer when the weather is hot and humid to help my makeup last.
