If you’ve been living under a rock, you’ll need to know that a makeup blender is basically the updated 21st Century version of a makeup sponge.
Most blenders allow your foundation to be effectively pressed onto your skin, as well as into your skin, for a more flawless, natural look. After all, they’re called beauty blenders for a reason—they blend your makeup exceptionally, and don’t usually leave streaks or blend lines. In addition to this, blenders transfer the product to your skin effectively, thereby allowing you to use less foundation, and get full coverage.
If you’ve got dry skin, a beauty blender is meant for you. This is because the bristles of the brush can irritate your skin and make it look flaky. The smooth, soft surface of a beauty blender is much gentler on the skin, and can help you flawlessly apply makeup without leaving you with a cake face.
As the best method of applying makeup with a blender is to ‘stipple’ it on in brief patting motions, using a beauty blender can be a tad bit time consuming. If you aren’t ready to spend time stippling on your makeup for a perfect look, it’s probably best to pass on the beauty blender. Also, as mentioned in the pros section, a beauty blender uses lesser product, and it’s because of this that it doesn’t work too well with light coverage foundations—you’ll only end up using a lot more foundation and will end up spending more.
Finally, a beauty blender needs to ideally be cleaned after every use—something that a lot of us don’t really have the time or patience for.
If you're looking for an airbrushed look, a makeup brush is your best bet. Brushes are a lot more bendable and can be extremely precise when it comes to the application of foundation. Makeup brushes are also ideal if you're the kind of person who prefers powder to liquid foundation—that's how versatile brushes are. It's also way easier to build coverage with a makeup brush.
Although you don't have to clean your makeup brushes as often as a beauty blender, a makeup brush does need to be cleaned, and requires a special cleanser—a cleanser that is usually quite expensive.
In addition to this, there's always the risk of a brush leaving your face looking streaked, and can also make your blend lines visible, which makes your look seem totally unnatural.
