After you apply foundation, your face needs one thing: powder. Powder helps to set your foundation. It also evens out the tone and helps your foundation to last through the day or evening. To apply that powder, you'll need a brush. But what kind?
Powder brushes come in many shapes and sizes, but don't be overwhelmed. Simply look for a brush that has a full head. The bristles should feel fluffy and light. If the bristles are too hard, your makeup will go on splotchy. A softer brush is also less likely to irritate your skin. Some people like a brush with a long handle; others prefer a short handle. It's really just a matter of personal preference.
