Here are the steps to apply powder foundation:

1. Swish a kabuki or rounded foundation brush over the powder foundation. Move the makeup brush back and forth over the pressed powder in short strokes to coat the bristles.
2. Press the powder over your skin with a slight rolling motion. Use gentle pressure to roll the brush over your skin, working from the center outward, to apply the foundation. Do this all over your skin for a smooth natural look.
3. Build coverage where you need it. If you need more coverage in certain areas, use a smaller brush or sponge to apply more powder foundation.
4. Use a damp beauty sponge for heavier coverage. Wet your beauty sponge and squeeze out any excess water before dipping it into your powder foundation. Then, use it to apply the foundation in areas where you need more coverage.
