What the gurus are saying

The brush's distinctive paw-shaped curve fits snugly into the inner corner of the eye and applies concealer through stippling motions rather than dragging, which keeps product concentrated where discoloration needs coverage and away from fine lines and wrinkles. Gurus praise how the soft fibers blend seamlessly without streaks or patchiness and lay down just enough concealer for full coverage without excess that settles into creases, making it especially valuable for mature skin. The recommendation is to pat and stipple rather than swipe.

"This is unlike any brush that I've ever encountered. This is amazing. It's like this little kitten paw. This works so well for applying under eye concealer because it's the perfect shape, especially if you have prominent under eye hollows, and it's also really good for getting right up in here and for just patting the concealer on. This works really well for applying under eye concealer without it going on streaky. It really blends it in really nicely."

"This is the best concealer brush. You guys know how much I love this and how much I use it. The way that this blends out your concealer, it just curves around all the hard-to-reach areas. It perfectly buffs concealer up under the eyes. Phenomenal."

The Makeup I'm Thankful For This Year 🥹
"I'm going to use this with the A506 brush from BK Beauty. This brush has basically broken the Internet, it's amazing, and it's so fun to see how successful this brush has been, so well-deserved though. It's like one of the best out there. If you haven't tried this, this would be a great present to yourself. It really is one of those things that makes a difference in the way your makeup applies, and it's just the perfect texture and size and everything to really make your concealer apply so flawlessly, especially under the eyes."

"This is a brush that they created with Angie Hot and Flashy. It's the A506 and it is the most perfect concealer brush ever, ever, ever. It has a very similar shape to the 109 in that like half dome curvature situation. It is so perfect to buff and blend out concealer to the point where you get precision, you get blend. It is divine. I love this one."

"I definitely recommend getting a really good quality concealer brush. This is my A506 brush with BK Beauty. And this is very similar to their foundation brush. I actually modeled it after that one. Using a blending sponge, it just removed too much of the concealer and I didn't get enough coverage. Once I created this brush, oh my gosh, it really changed my concealer game. You press it and stipple it rather than dragging. So basically, I start patting it into the concealer, working it into the brush. I just bring it across using those same patting motions. And you can see that even with just little patting motions, it spreads the concealer under my eyes, but it's leaving most of the concealer concentrated at the inner corner where I have my discolorations, and it's putting just the tiniest bit of concealer out here where most of my bigger wrinkles are. So when I smile, I have my crows feet, and I don't want my concealer settling in those wrinkles and making my skin look wrinklier than it is. So that's why it's best to keep it more at the inner corner. Just stipple it across and that way you get the least amount on here because definitely with older skin and makeup, less is more. But look how beautiful and smooth that looks."

"This is an excellent concealer brush. It's a viral brush. It's so good for really detailed work. The right size and it actually curves to the shape of your nose, follows along it. It's excellent. The longer fibers of this brush I'm going to use to blend out the edges of the concealer so it really is seamless and it melts into the rest of the complexion."

"It is so soft and so lovely and it works great with the SE concealer, my Lancôme concealer, just about any concealer. It's really just like a combination of the softness and the fluffiness of this brush that just lays down concealer so seamlessly and so smoothly. It never leaves any streak marks, it never leaves it patchy or weird looking."
The NEW Product YOU Asked For! + Anniversary Sale!
"If you have never put on your under eye concealer and liked the way it looked, whether you use your finger or a sponge or some other brush, this is the brush to try. I had tried all the brushes out there, used my finger, used a sponge, until this. Now this is the only thing I use and I love it so much. It really does make my concealer go on so perfectly. It fits so perfectly right into that corner of my eye. It's just an amazing brush. The quality of these brushes is so good. The brush fibers are so soft. They never poke, they never prickle, they never make your skin feel bad, and they don't tug on your skin either, which is a problem that we have once we get more mature and our skin gets to be a little bit looser. I use them all the time. I use them every single day in tutorials, in videos, behind the scenes, and nothing has ever happened."

"The number one brush that I would recommend is my A506, this is my concealer brush. I developed this to be kind of a mini version of the BK-101, which is another one of my all-time favorite brushes, and it was the exact shape of that that I wanted to translate into a mini one that would fit perfectly right into the inner corner of the eye. So this fits perfectly and it's so soft. There's never a brush mark, never a streak. It just shears it out so perfectly, but also lays down the right amount so that you do get the coverage you want, but you don't get any excess that is going to settle into your wrinkles. I just love it. I use it every single day."

"The A506 Concealer Brush is like a mini cat's paw, the perfect shape to get right into the inner eye area. It makes it so easy to spread just the right amount of concealer, doesn't pick up any product, and lays it down without any marks, so you get nice full coverage with less product. It can be bought separately and makes a great stocking stuffer."
