I'm not one for pressed powder, but blot powder is a different story: it doesn't add much powder; removes oils beautifully; and lasts a long time. My first love is M.A.C.'s blot powder, but I have found a close second for those occasions when you can't find M.A.C.'s or if they are sold out in your shade: Sephora's Mineral Matte Touch-Up Powder.
It's formulated without parabens and synthetic fragrances, and comes in one universal shade: translucent.
Although M.A.C. is my first love, I'll take Sephora's version in a pinch. $18.
