Initial Setup: Your Real Techniques Expert Face Brush comes ready to use. For optimal hygiene and to remove any manufacturing residues, a quick, gentle wash with mild soap and warm water is recommended before its first use. Rinse thoroughly and allow it to air dry completely. Compatibility: This brush is optimized for cream and liquid foundations. Its dense, firm bristles are perfect for picking up and blending these types of formulas smoothly. While it can be used for other cream-based products like contour or blush, its primary design focus is foundation application. It is generally not recommended for powder products as its dense structure may pick up too much powder, potentially leading to a cakey finish. Care and Maintenance: - Cleaning: For optimal performance, hygiene, and longevity, clean your brush weekly or bi-weekly, depending on your frequency of use. Use a gentle brush cleanser or mild soap (like baby shampoo) and lukewarm water. Gently lather the bristles, rinse until the water runs clear, and gently squeeze out excess water with your fingers or a clean towel. - Drying: After cleaning, reshape the bristles to their original form. Lay the brush flat on a clean towel or use a brush drying rack to hang it upside down, allowing it to air dry completely. Avoid drying vertically with the bristles pointing upwards, as water can seep into the ferrule and loosen the glue over time. - Storage: The brush features a self-standing design, allowing it to stand upright on your vanity or in a brush holder. This protects the bristles from damage and keeps them hygienic.
