The ULTIMATE CONCEALER DUO is designed with 2 brushes to cover and blend imperfections for an even and fresh complexion. COVER: After applying foundation, use the Detail Concealer to precisely cover spots or discoloration. BLEND: With the Airbrush Concealer, blend out color deposit previously applied for a smooth base. Cleaning Tips: 1. If it's a brush you use daily, it is recommended that you wash it weekly using the EcoTools Brush Shampoo and warm water. 2. Lather the bristles with our EcoTools Brush Shampoo and rinse under water until the water runs clear. 3. Try not to fully submerge the base of the bristles in water or your cruelty-free bristles may detach from the form. 4. After rinsing, smooth brush head back into original form and lay flat to dry. 5. Let dry overnight and wake up to a refreshed brush for your morning makeup routine! 6. For a simple daily cleanse, try out our EcoTools Cleansing Cloths.
