I'm back to my foundation brush! I bought it awhile ago, but I thought it was a hassle, and went back to my fingers. After reading a bunch of posts saying that a brush gave them a more flawless finish and coverage, I dug it out and gave it another go...whoa! It is a bit more work, since you have to wash it out regularly, but I think it is worth it. I realized I wasn't working the brush on my face enough before, so I was pretty much doing all of my blending still with my fingers. So far, I think it works better with cream compact foundations. My liquid streaked a bit, but I put my foundation on only a couple minutes after my moisturizer, since I think it blends better that way, and I can do extra blending with my fingers...And I also use it with the Dream Matte mousse, just for hygiene reasons (diligently washed out my brush DAILY)
Whatever works for you though, is what's important...Someone else mentioned how different makeup works on us, so experimenting with several methods is best, although I can't justify sponges, since they just mop up product, and nothing ends up on your face; absolute waste, if you ask me.
