With its ultra-fine, densely packed bristles that feel like rich velvet, this makeup brush is unlike anything you’ve experienced. It combines the best of a sponge and brush, seamlessly blending moisturizers, foundation, blushes, bronzers, and powder. The finished look gives an airbrushed effect with no streaks. Plus, the innovative design is sculptural and functional. The tilted handle keeps it snugly in your hand. And the domed, angular shape fits nicely near the corners of your eyes and makes contouring easy.

  • Materials: Nylon bristles, PBT plastic handle
  • Care: Soak the brush head in your brush cleaner of your choice for 3-5 minutes. Rinse with warm water and let air dry. Make sure to clean the brush with brush cleaner after each use for sanitation and longer brush life
  • Crafted to blend foundation, powder, cream, moisturizer, and primers seamlessly into your skin, creating an airbrushed effect
  • Pointed tip fits underneath the hollows of the eye and helps contour facial features
  • Angular shaped, dome-like brush blends makeup into skin to achieve a professional look with streak-free, flawless coverage
  • Velvet-like bristles are densely packed with ultra-fine fiber that provide a streak-free finish
  • Ideal for home use or travel—includes a slip-off cap to protect the bristles from germs, dirt, and dust
  • Self-standing design keeps the brush head from ever resting directly on surfaces to prevent germs and contamination
  • Compatible with liquid, cream, or powder makeup. Uses very little of product with fullest coverage
  • Made in Korea
  • Dimensions: 6.25" x 1"
  • Weight: 0.06 lb

It Made a Difference!

12/14/2018 by Joyce

I bought 2 of these - they were supposed to be gifts. But I tried one and was happily surprised to see that using this product made a real difference.

My "old" method was to put on my foundation and smooth it with a small sponge. When I used Wow Brush I could see how much smoother the foundation was on my face!

So I am keeping both of them! :)))

This brush is so soft like velvet and the bristles are so tight that when you put on foundation or concealer it goes on with little to no streaks it distributes product evenly! Great product my First oval brush and I am a fan!More > < Less

I use this every day for applying my daily under eye liquid makeup. Works exactly like I need because the unique shape of the brush gets in the weird parts that normal brushes can't reach. Don't know how I lived without it!More > < Less

About Cailyn Cosmetics

Airbrushed Effect

What’s so “wow” about Cailyn Cosmetics’ O! Wow Brush? First, the patent-pending design. It looks like a sculpture, but each artistic feature is actually a carefully designed benefit.

The bristles are ultra-fine and so densely packed they feel like velvet. Touch the lush surface and you’re likely to exclaim (as we here at The Grommet did), “Oh, wow!” This incredible surface offers the best of a brush and sponge, giving you complete, streak-free coverage with an airbrushed effect.

The pyramid base lets the brush stand all on its own, with an alluring tilt to the handle that’s designed to fit snugly in your hand. That means greater stability and precision. And the pointed tip and domed angular shape make blending creams and powders seamless and contouring effortless.

Cailyn's other innovative makeup brushes include the 4-in-1 Eye Brush and 4-in-1 Lip Brush. Both are single applicators with two removable dual-end brushes. The ends have different shapes that let you create dozens of different eye and lip looks with a single tool.

All in all, Cailyn makes it super easy to create a whole lot of wow.
