Review & Usage

Urban Decay Good Karma Optical Blurring Brush is a medium-sized, dome-shaped foundation brush that was designed specifically to apply the brand’s own Naked Skin Weightless Ultra Definition Liquid Makeup. However, it can also be used to apply other liquid, cream, and powder foundation as well. The brush handle (made from recycled aluminum) has a purple-ish metallic color and flat bottom so it can stand on its own if you wish to store it that way. The brush also has a wider area near the top of the handle making it super easy to hold and control the coverage while you’re buffing in your foundation.

The bristles are two-toned synthetic and cruelty-free. They are densely-packed to distribute the pigment evenly on the face. It is possible to achieve a near airbrushed finish with this brush when you apply your foundation with a stippling method and then gently buffing it in to the skin with circular motions. I have never had a streaky or cakey finish when using this brush. I like how the bristles are soft but still firm enough that they don’t flare out too much — this makes it possible to maneuver into the nooks and crannies of the face.

The only small drawback with this brush is that it requires a little effort to clean (due to the dense bristles) and can take a full day or two to dry completely after cleaning. Otherwise, it’s a great tool to have for a flawless (foundation) face! :)

  1. O_O Two days to dry? Do you live in a tropical rainforest?! ;-)

    Sounds and looks like a wonderful brush. The name alone makes me want to literally get my hands on it asap…

      LOL! Well, I dry my brushes in Brush Guards so maybe that’s why it takes a little longer than usual for them to dry. :D

    I really liked reading your post. I was just curious, what kind of brush cleaner are you using that it takes so long for the brush to dry or is it just the because it’s so dense???

    Looks great! Have you tried Marc Jacobs foundation brushes? I need a great foundation blending brush — must be synthetic, because I found out after buying some beautiful Japanese brushes (Koyudo) that I am allergic to goat! (Hello hives.) Go figure.

    1. says: Jaa

      Yes, I have both of them (The Face I & II). I think the Face II is better if you’re looking for a full coverage with an airbrushed finish (due to the dense bristles). The bristles of the Face I are loose in comparison and flare out quite a bit so I only reserve it for when I need a sheerer coverage.

      Wow, you’re the first person who I heard allergic to goat! 8-O Goat hair is super duper soft, though!!!

      1. says: JK

        Thanks for the feedback! Face II it is. Thankfully I can still use goat for eyes and blush… I guess the extra buffing with a face brush though was just too much.

    Hey Jaa, I’m glad to hear this one works well! I only own one UD brush, which is the duo-ended one from Naked 2. Annnd I hate it. It’s so stiff. I can hardly do anything with it! Maybe the regular brushes are softer and perform better? Hmm.

    1. says: Jaa

      Oh those are terrible for applying powder eyeshadows, LOL! They are great for cream formula, though! The regular brushes are way softer and yes, perform much much better! :)

        1. says: Jaa

          They are pretty….. small…. I don’t think they are a necessity. The pointy tip of the original one pretty much works in the same way… but the cuteness factor, though! ;D

    Hi Jaa,
    My goodness, how many brushes do you have:)? I am in love with my beauty blenders and probably going to buy the new Dior Star foundation with the sponge so I will give this one a miss this time:)

  6. says: Carolyn

    Such beautiful photos, Jaa! The brush sounds really great with the exception of the drying time. Do you have the Real Techniques Expert Face Brush? I just ordered one based on Kristen’s suggestion!!

  7. says: Lily

    I’ve read mixed reviews about this brush and like Sunny, I only even tried their brush in the Naked2. Same opinion about that brush too. For foundations, I love my RT Expert Face brush and my Tom Ford cream foundation brush. The latter is such a dream to apply :-)

  8. says: Sylirael

    Ugh, I totally want this. I have no reason to want it, really, since I almost never wear liquid foundation (a BB cream is the only one I own), but it’s Urban Decay, and looks eminently fondle-able.

    I really think you need a ‘fondle-ability’ section in your score for brushes, Jaa ;-)

    1. says: Jaa

      You are the biggest fan of UD, Syl! ;D Had no idea you don’t wear liquid foundation! Any reason why? 8-0

      Fondle-ability – LOL! GREAT IDEA! ;D This one I’d give a 10!

  9. says: Dee

    Have it , love it! It does take a tad longer to dry /clean but thats no deal breaker for me. The price was a BIG bonus too for the quality!

  10. says: Gig

    It blends the foundation very well. I thought I was the only one who thinks that. It takes like 2 days to dry. But I’m in love with it anyway, P’jaa :)
