Allow to settle in and then remove any excess powder with a Powder Rouge Brush.

If you have worked with Cake Make-up and Eyeshadow/Rouge then there is no need to powder off.

BRUSHES POWDER ROUGE = Brushes Powder/Rouge
CAKE MAKE-UP = Cake Make-up
EYESHADOW/ROUGE = Eyeshadow/Rouge
By powdering off, you have fixed the make-up.
Hint: if someone has expressive dark eyelashes or is very young, you can make the eyelashes 'colourless' by applying a little Water Make-up (Pure) to them in a light skin colour.
Colour the hair and the eyebrows grey using Grimas Water Make-up (Pure). For very dark hair; you use white otherwise use grey. For the head hair you use a sponge or a toothbrush; for the eyebrows or a moustache you use a (artist's) brush.
