Use the TSUTSU FUDE Concealer Brush to buff and blend concealer, or tap concealer on with it to build additional coverage where needed. HOW TO CLEAN: Always wipe the brush with a tissue immediately after use. To prevent caking, wash the brush and dry it completely before using a product with a different texture. Wash the brush using a mild soap or face wash to remove product buildup. Rinse thoroughly and remove excess water with a dry towel or tissue. Avoid soaking the brush in cleansing solution as this may cause color of the brush to fade. Lay flat and dry completely before use.
