I LOVE this powder! I have oily skin and often go through very long days where I have few opportunities to blot or touch up my foundation. I've tried several mattifying primers and foundations in hopes of staying matte all day, but without this powder I am nothing. I put it on right after my foundation and concealer and it completely seals in anything that, originally, might slide around. On good days, it lasts all day, and on bad days, it lasts for at least seven hours. I usually apply it with a brush, but it works very well when applied with a beauty blender, too, and makes my skin very smooth and soft. That being said, it definitely takes some getting used to when applying, and I can definitely see it being a problem for dryer skin.
