Take the latex prostetic out of the box and place it on the skin to get an impression of whether the edges are a good fit and where it is soon going to be glued on.
Mark out the edge on the skin with a make-up pencil or some Transparent Powder
Everything that is going to be coloured in a skin tone - except for the edges - must be pre-coloured slightly with red to suggest naturally perfused skin. To do this, apply Grimas Special Effects Powder 504 or a red Grimas Eyeshadow/Rouge using a Make-up Sponge or Powder Rouge Brush.
Then use a sponge to apply a covering layer of Grimas Camouflage Make-up Pure in the desired skin shade. Work directly from the stick or spatula.
Note: don't use Crème Make-up Pure for skin tones, but use Grimas Camouflage Make-up Pure.
Put a piece of wadding in the nose to maintain its shape and to absorb perspiration.
