To fix and mattify, you can powder the Foundation off with Grimas Fixing Powder or Make-up Powder. If you want to affect the colour more, you can use Grimas Compact Powder or Colour Powder. Make-up Powder can be applied with a Grimas Velour Powder Puff, a Powder Puff or a Powder Rouge Brush.
You take with a clean Powder Puff loose powder from the box, dab the excess powder off on the hand and then apply the powder to the make-up with a light, dabbing motion.
