The Wonder Cover complexion brush is designed for full coverage of liquid and cream foundation coverage in less time. The brush can be used wet or dry. With a simple sweep, you camouflage common skin problems such as rosacea, hyperpigmentation and blemishes. Moisten brushes for a cleaner application. Use the brush wet or dry. To begin with, dab the top of the brush in a small amount of foundation. Gently slide color starting in the center of the face and working outward toward the hairline. Use long and short strokes to cover the entire face and prevent streaks.
