First, apply the makeup shade of your choice. Move the brush bristles along exclusive textures to remove color. Use a back and forth motion for pressed powder products like blush, highlighter, contour/bronzer, eyeshadow, etc. Use a circular motion for cream or liquid formulas and eyeshadows on softer, less-dense blending brushes. Now, the brush bristles should be free of residual color. Note: There may still be color stains (but no residue) on the bristles. Select the next makeup shade of your choice and apply it using the same brush. Once both sides of the mat are covered in makeup residue, wash it with SigMagic® Brushampoo Liquid or Foam.
