I've found Beautyblender, that pink egg-shaped sponge, indispensable for blending liquid and cream makeup. I rely on it to blend concealer.
But applying loose mineral powders with Beautyblender? That's a new one to me. Koren Zander of EnKoreMakeup shows you how in the following video. Be prepared - the video runs 15 minutes.
I tried Koren's method, which resulted in weightless yet complete coverage and a matte finish that lasted all day. No need to use blotting papers!
You may find Beautyblender at Amazon.com and Sephora.com, among other outlets.
