So, I purchased the Mac 187 "stippling" brush a few weeks ago on Ebay after hearing rave reviews. Most claimed that the brush helped foundation and blush appear airbrushed. Well, after my first time using it, I was in looovveee! I absolutely adore this brush and can vouch that it does all the good things that people say. It retails for around $42 I believe, but if you search on Ebay, you can find it a lot cheaper! Can't wait to try the brush with the Revlon Photoready foundation.
