While we wish we could give you a concrete answer, as with most makeup questions, the answer will lie in your personal preference, as well as the consistency of your go-to blush.
The Benefit of Applying Blush With a Makeup Brush
Makeup brushes are the tool that many makeup wearers are most comfortable with, as most people start doing their makeup with a brush. Brushes are easy to use, come in a variety of sizes, and they allow for a very smooth and even application, which is especially important when it comes to blush.
The Benefit of Applying Blush With a Makeup Sponge
The sponge diffuses the product nicely onto the skin, and since blush is a product that can easily appear too bright on the face, it’s a nice way to ensure that you don’t go overboard.
The Benefit of Applying Blush With Your Fingers
While you may think this method of application is less sanitary than makeup brushes or won’t give you as good of a result, won’t be worth the stained fingers, using your fingers to apply your blush allows for a certain level of control, as you can see and physically feel how much product you’re about to apply.
