When I finally purchased it, I was at ULTA with my toddler (note to self: do not buy foundation with a toddler in tow). Obviously things were a tad rushed, so rather than actually applying the foundation to my jawline as I should have, I held up the transparent plastic thing that UD claims will give you your shade number. I bought 1.0, which I expected because my friend Phyrra was 0.5, and generally I'm just a tad darker than her. Luckily the ULTA SA put in a little sample shade pack from UD. Because that 1.0? Waaaay off. I was a lot closer to the 2.5 in the shade pack. I returned it a little later when it was obviously much too light. Later, Urban Decay sent me the foundation (and the brush here), and it turns out that 3.0 is the best match for me.
Any foundation that gives me such great looking skin (you can't even see that foundation) and lasts for well over 12 hours is definitely one I can recommend.
While this is a pretty big brush, it's still smaller than my big kabuki brushes. It's slightly domed and the bristles are a bit stiff, but do bend easily and are fairly soft.
I've been using the Optical Blending Brush to slightly stipple and blend my foundation, and the results have been much better than my Beauty Blender. I have noticed that there are some foundations that the brush is better for, and some that the Beauty Blender is better for. In general, the brush works better with more liquid foundations, the thicker the foundation (such as the new Stila Stay All Day foundation, which I'm reviewing tomorrow) are better off with the Beauty Blender.
Do you use a brush or a sponge with your foundation? Do you have a great blending trick that you can share?
