I use this w/ Revlon's stick concealer. I was really skeptical about this brush, as stick concealer is typically hard to apply without it caking, and the cost of this brush didn't make me think automatically that it'd give professional results. I'd actually given up on concealer because of those very issues. But I realized that, as I got older, my foundation could use a little help in covering my flaws! And I'm happy to report that I was wrong- concealer can be applied easily & last all day, when I use this brush. It made the stick concealer go on PERFECTLY. It never cakes during the day. Application is done in light, feathery strokes, and I find this brush keeps me from wasting the product, too. Very little is needed when using this brush to apply the product. No bristles come out, the brush is just the right length to fit in my makeup bag, and feels good in the hand. The bristles are smooth & soft, but firm, which is needed in this capacity. Great little brush!
